Don't forget pthread_exit() and longjmp() (there should be a base class 
ala thread_termination_request for thread cancel and thread exit 
exceptions). Time to kill ugly forced unwind altogether (getting rid of 
undefined behavior resulting from "more restricted behavior" for longjmp() 
would not hurt either).
