-// The routines exported by this module are subtle.  If you use them, even if
-// you get the code right, it will depend on careful reasoning about atomicity
-// and memory ordering; it will be less readable, and harder to maintain.  If
-// you plan to use these routines, you should have a good reason, such as solid
-// evidence that performance would otherwise suffer, or there being no
-// alternative.  You should assume only properties explicitly guaranteed by the
-// specifications in this file.  You are almost certainly _not_ writing code
-// just for the x86; if you assume x86 semantics, x86 hardware bugs and
-// implementations on other archtectures will cause your code to break.  If you
-// do not know what you are doing, avoid these routines, and use a Mutex.
-//
-// It is incorrect to make direct assignments to/from an atomic variable.
-// You should use one of the Load or Store routines.  The NoBarrier
-// versions are provided when no barriers are needed:
-//   NoBarrier_Store()
-//   NoBarrier_Load()
-// Although there are currently no compiler enforcement, you are encouraged
-// to use these.
