[VSDK] Semaphore freeze after a crash

[Totte Alm]

Eric, Ruslan!!

I've tried to make Ruslan fix this bug for 6 months!!
Its because of the fact that deep inside VSDK, there is a MUTEX that is  
created with the WRONG parameter, probably proted Windows code, as  
Windows
Mutexes are REENTRANT by default unless you explicit specify POSIX  
Mode, but on UNIX Mutexes are NOT REENTRANT, hence the bug doesnt
show up in the VSDK for Win32.

If you have code to preproduce it, please send it to Ruslan as he  
"denies the existance of that mutex"!
I KNOW its deep down in the FBL stuff, and its becuase the mutex stuff  
is classes them self, and its hard to try to folow WHAT is really  
compiled when
we only have parts of it and not KNOW what really inside the VSDK  
Framework and really gets called.

Sorry for the rough language, but I've really really really tried to  
make Ruslan fixc this one, but he cant find it...
