NOW, what is dangerous with it is that you must NEVER dereference pointers to automatic variables for another process... those variables simply will not exist in your new process context...
Guess why other OS's don't implement wait-queues the way we do? ;-) Our scheme depends upon being able to reference data residing within the stack frame of any thread at any given time.
