 // 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.
