    You never can. You never know when a libarary might commandeer your 
thread and go near a sync object. In order to support Suspend/Resume 
threads, you must make sure your entire design, from the ground up, is 
suspension safe. This is a (potentially) huge cost that pthreads decided not 
to require every implementation to take.
