I'm not really sure if this is right, but if I understand correctly you access 
this global variable without locking, assuming that the access to an integer 
is an atomic operation. Depending on the platform and the implementation this 
might not be true and lead to the experienced effect.

But again - may be I'm plain wrong ...
