Just for the record, if all the threads run to completion, and the mutex 
do their job, the number should have been 300000. Any other number seems 
to indicate that there was a problem with the mutex. If a mutex failed 
to be granted we should have seen messages, which didn't happen either.

This problem is for both Windows AND wine. I can only deduct that I'm 
doing something wrong. Maybe named mutexes are not shared like I thought 
they are? When I try to create the mutex only once and share the handle 
I get a lot of failed locking responses, also on Windows. Then again, 
when I use the original code, even on windows, the number is not a 
multiple of 1000, which suggests that not all increments happened.

The only explanation is that there is a bug in the win32 code. But what?
