Go through all the signals (with the exception of SIGKILL and SIGSTOP
since they cannot be added to a process's signal mask) and add each one
to the signal mask. Every time a signal gets added to the signal mask
(using the pthread_sigmask() function),  make sure that all signals added
before it in preceding iterations before it, exist in the old signal set
returned by the pthread_sigmask functions.
