Do not use named semaphores on Windows since they are system wide

Hopefully this resolves glitches on hyperthreading machines.
Apart from using unnamed Semaphores, pthread-w32 includes additional locks
(guess: mem-barriers), a fallback implementation and windows-specific
tricks that I'd rather not want to know about :)
