I'm assuming you're replying to my remarks at 
http://article.gmane.org/gmane.comp.gnu.mingw.devel/948

If you have the time, I would appreciate it if you could show me why my 
suggested short implementation is semantically inappropriate.  I've 
reexamined it, and checked some Internet references, and I can't figure 
out the problem with it.  See a similar implementation using 
InterlockedExchange, the lightweight mutexes used for shared_ptr in 
Boost: http://www.boost.org/boost/detail/lwm_win32.hpp

Speaking of Boost, a recent Windows multithreading-related post to the 
Boost mailing list may be of interest to some:

Thank you for your time,
