Comment(by steven_watanabe):

 Okay.  The problem is
 [source:trunk/boost/thread/pthread/once.hpp_at_45865#L49 once.hpp line 49]
 and [source:trunk/boost/thread/pthread/once.hpp_at_45865#L72 once.hpp line
 72].  For this to work, we need atomic read and write.  I'm not sure
 whether this is a real problem or not.  At least it should be explicit.
