	When we enter a directory, fork and exec makeicons. Then check
if there is a subdirectory called .xfiler. If there is, read icons from
there.
	The script exits with an exit code of 1 if no icons were generated
and 0 otherwise. If we got a 0, reread the .xfiler directory and redraw
the window.
	When we fork, we remember the PID of the most recently launched
makeicons in the variable iconpid. That is how when we wait() on the
terminated child, we know that it is makeicons that has terminated and
not some other random subprocess.
