+TODO
+====
+
+A collection of ideas and notes about stuff to implement in future versions.
+"#NNN" occurrences refer to bug tracker issues at:
+https://github.com/giampaolo/psutil/issues
+
+
+HIGHER PRIORITY
+===============
+
+ * OpenBSD support.
+
+ * #371: CPU temperature (apparently OSX and Linux only; on Linux it requires
+ lm-sensors lib).
+
+ * #269: expose network ifaces RX/TW queues. This should probably go into
+ net_if_stats(). Figure out on what platforms this is supported:
+ Linux: yes
+ Others: ?
+
+ * Process.threads(): thread names; patch for OSX available at:
+ https://code.google.com/p/plcrashreporter/issues/detail?id=65
+
+ * Asynchronous psutil.Popen (see http://bugs.python.org/issue1191964)
+
+ * (Windows) fall back on using WMIC for Process methods returning AccessDenied
+
+ * #613: thread names.
+
+ * #604: emulate os.getloadavg() on Windows
+
+ * #269: NIC rx/tx queue.
+
+
+LOWER PRIORITY
+==============
+
+ * #355: Android support.
+
+ * #276: GNU/Hurd support.
+
+ * #429: NetBSD support.
+
+ * DragonFlyBSD support?
+
+ * AIX support?
+
+ * examples/taskmgr-gui.py (using tk).
+
+ * system-wide number of open file descriptors:
+ * https://jira.hyperic.com/browse/SIGAR-30
+ * http://www.netadmintools.com/part295.html
+
+ * Number of system threads.
+ * Windows: http://msdn.microsoft.com/en-us/library/windows/desktop/ms684824(v=vs.85).aspx
+
+ * #357: what CPU a process is on.
+
+ * Doc / wiki which compares similarities between UNIX cli tools and psutil.
+ Example:
+ df -a -> psutil.disk_partitions
+ lsof -> psutil.Process.open_files() and psutil.Process.open_connections()
+ killall-> (actual script)
+ tty -> psutil.Process.terminal()
+ who -> psutil.users()
+
+
+DEBATABLE
+=========
+
+ * psutil.proc_tree() something which obtains a {pid:ppid, ...} dict for
+ all running processes in one shot. This can be factored out from
+ Process.children() and exposed as a first class function.
+ PROS: on Windows we can take advantage of _psutil_windows.ppid_map()
+ which is faster than iterating over all pids and calling ppid().
+ CONS: examples/pstree.py shows this can be easily done in the user code
+ so maybe it's not worth the addition.
+
+ * advanced cmdline interface exposing the whole API and providing different
+ kind of outputs (e.g. pprinted, colorized, json).
+
+ * [Linux]: process cgroups (http://en.wikipedia.org/wiki/Cgroups). They look
+ similar to prlimit() in terms of functionality but uglier (they should allow
+ limiting per-process network IO resources though, which is great). Needs
+ further reading.
+
+ * Should we expose OS constants (psutil.WINDOWS, psutil.OSX etc.)?
+
+ * Python 3.3. exposed different sched.h functions:
+ http://docs.python.org/dev/whatsnew/3.3.html#os
+ http://bugs.python.org/issue12655
+ http://docs.python.org/dev/library/os.html#interface-to-the-scheduler
+ It might be worth to take a look and figure out whether we can include some
+ of those in psutil.
+ Also, we can probably reimplement wait_pid() on POSIX which is currently
+ implemented as a busy-loop.
+
+ * Certain systems provide CPU times about process children. On those systems
+ Process.cpu_times() might return a (user, system, user_children,
+ system_children) ntuple.
+ * Linux: /proc/{PID}/stat
+ * Solaris: pr_cutime and pr_cstime
+ * FreeBSD: none
+ * OSX: none
+ * Windows: none
+
+ * ...also, os.times() provides 'elapsed' times as well.
+
+ * ...also Linux provides guest_time and cguest_time.
+
+ * Enrich exception classes hierarchy on Python >= 3.3 / post PEP-3151 so that:
+ - NoSuchProcess inherits from ProcessLookupError
+ - AccessDenied inherits from PermissionError
+ - TimeoutExpired inherits from TimeoutError (debatable)
+ See: http://docs.python.org/3/library/exceptions.html#os-exceptions
+
+ * Process.threads() might grow an extra "id" parameter so that it can be
+ used as such:
+
+ >>> p = psutil.Process(os.getpid())
+ >>> p.threads(id=psutil.current_thread_id())
+ thread(id=2539, user_time=0.03, system_time=0.02)
+ >>>
+
+ Note: this leads to questions such as "should we have a custom NoSuchThread
+ exception? Also see issue #418.
+
+ Note #2: this would work with os.getpid() only.
+ psutil.current_thread_id() might be desirable as per issue #418 though.
+
+ * should psutil.TimeoutExpired exception have a 'msg' kwarg similar to
+ NoSuchProcess and AccessDenied? Not that we need it, but currently we
+ cannot raise a TimeoutExpired exception with a specific error string.
+
+ * process_iter() might grow an "attrs" parameter similar to Process.as_dict()
+ invoke the necessary methods and include the results into a "cache"
+ attribute attached to the returned Process instances so that one can avoid
+ catching NSP and AccessDenied:
+ for p in process_iter(attrs=['cpu_percent']):
+ print(p.cache['cpu_percent'])
+ This also leads questions as whether we should introduce a sorting order.
+
+ * round Process.memory_percent() result?
+
+ * #550: number of threads per core.
+
+ * Have psutil.Process().cpu_affinity([]) be an alias for "all CPUs"?
+
+
+COMPATIBILITY BREAKAGE
+======================
+
+Removals (will likely happen in 2.2):
+
+ * (S) psutil.Process.nice (deprecated in 0.5.0)
+ * (S) get_process_list (deprecated in 0.5.0)
+ * (S) psutil.*mem* functions (deprecated in 0.3.0 and 0.6.0)
+ * (M) psutil.network_io_counters (deprecated in 1.0.0)
+ * (M) local_address and remote_address Process.connection() namedtuple fields
+ (deprecated in 1.0.0)
