On the other hand, our Windows implementation of condition::wait follows the algorithm laid out by Alexander Terekhov's "Algorithm 8a" posted in comp.programming.threads on April 27, 2001 (and noted as such in that file Alexander). In this case the wait() function does not differ depending upon the recursiveness of the mutex.
To clarify: does your implementation support waiting on a recursive mutex that has been locked more than once, temporarily decreasing its lock count to zero to allow other threads to acquire the mutex while the original thread is blocked by the wait?
That was the intent. But I stand corrected. I evidently got it wrong except on Mac OS X where I do explicitly decrement the count to 0 of the pthread_mutex during a wait (recursive mutex case only). Looks like I need to dig back into this on other platforms... -Howard
