- * LSPs are evil little bits of code that are allowed to inject into our
- * networking stack by Windows.  Once they have wormed into our process
- * they gnaw at our innards until we crash.  Here we force the buggers
- * into the light by recording them in our crash information.
- * We do the enumeration on a thread because I'm concerned about startup perf
- * on machines with several LSPs.
