Personally, I'm not convinced that it will make a difference outside of
Windows. The fix is to make sure a lock gets destroyed when done and the
function exits. On Windows the lock gets created and memory is allocated
for it outside of the function using it and needs to be explicitly
destroyed, but my understanding of pthreads was that this worked
differently on Unix and the lock structure would be automatically
destroyed when the function is exited since the lock was local to the
function.

I'd be interested in seeing the results of this.
