     The p\bpa\bau\bus\bse\be() function forces a process to pause until a signal is received
     from either the kill(2) function or an interval timer.  (See
     setitimer(2).)  Upon termination of a signal handler started during a
     p\bpa\bau\bus\bse\be(), the p\bpa\bau\bus\bse\be() call will return.
