*oh* Before the wait? That's not good. This cries for race conditions
and subtle deadlock situations.
thread synchronization uses this and takes care of it by calling
RTLeventstartwait which locks the associated mutex.
As far as I just read code and comments, it does it for Windows to get
Unix behaviour, although I don't see the point here, because this just
forces the race condition the POSIX-Threads implementation actually
tries to circumvent with this associated mutex.
I'm not even sure, if Unix actually clears the event. The man-pages
don't seem to indicate so.
