This exact problem had surfaced once in the past, and it had turned out 
that one specific non blocking call didn't have a corresponding wait. That 
was fixed (as far as I know). It is possible that we overlooked another 
one. 

Peter, could you give us more specifics about when you run into problem, 
so we can investigate ?

Thanks
