pause - wait for signal
The pause() library function causes the invoking process (or thread) to
sleep until a signal is received that either terminates it or causes it
to call a signal-catching function.
The pause() function only returns when a signal was caught and the sig
nal-catching function returned. In this case pause() returns -1, and
errno is set to EINTR.
EINTR a signal was caught and the signal-catching function returned.
