 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 sigprocmask() function),  make sure that all signals added
 before it in preceding iterations before it, exist in the old signal set
 returned by the sigprocmask functions.
