Not the first time.  If ... TOCK is printed once (after TICK ... is
printed), then parent() set loc[0] and child()'s while loop ended.
Yes, parent and child both have called signal(), but the signal
apparently doesn't go through.

I think that parent() executes
	kill (loc[2], SIGUSR1);
before the child process executes
	loc[2] = getpid();
and the child process never receives a signal.
