Programs that play around with the screen, use raw mode, or otherwise
want to perform some action when the SIGTSTP (the one generated by ^Z)
occurs use this.  They catch the SIGTSTP signal and when they really
want to stop themselves they send SIGSTOP to themselves.  It's sort
of analogous to SIGTERM and SIGKILL.
