I=E2=80=99m trying to wait for all child processes to finish.  The lunix =
code my professor gave me for this was:
	while (wait(&wstat)>0)
		;
which I na=C3=AFvely translated as:
	while(waitpid() !=3D 0)
		;
which hangs.  Evidently waitpid returns something other than 0 when there=
 are no children, but what?  The man page wait(2) doesn=E2=80=99t say, no=
r does it point to the source for waitpid.
