I'm not sure how does that help given that they don't provide value 
dependent msync. Or do you mean "manually" coded "strong" decrement
using InterlockedCompareExchange/Acquire|Release/? If so, sorta yes,
but you know that I just hate volatiles... and it isn't clear at all 
whether (some new) MS compiler*** will inject unnecessary barriers 
(due to volatile accesses) or not.
