	I have just answered part of my own question. If you
background the process as in

sh /etc/rules.fw &

it works. You still get knocked off the remote connection but
the backgrounded process continues to run without a controlling
terminal and completes.

	The only remaining part of the question is:

If one modifies the firewall rules and wants to make sure they
are good, is there a more correct way to safely reload them from
the script?
