This is what CRITICAL_SECTIONs do, and I recall being told by Alexander Terekhov that it is suboptimal (threads take the slow path when they could take the fast path). My tests with a contended queue seemed to prove him right.

Unfortunately, I can no longer find his post where he explained that with Google.

Here it is:

Thanks. I'll have to look at Alexander's proposed swap-based implementation.

I've played with it a bit: http://www.pdimov.com/cpp/mutex.cpp but I suspect that there are a few errors in this old code... some of the reads are not atomic but need to be. Maybe we can give it a review and bring it up to Boost standards.
