	We've had problems here which the vendor "suspects" is due to
rancid rapid firing off commands during polling. I've done some ugly hack
work here to have rancid skip some commands for given platforms depending
on environment variable settings.
	What might be slightly less ugly would be to have an option to clogin
to set a delay between execution of commands. That might give the garbage
collection (referring to mem mgmt, not the overall OS here) a chance to
catch up between commands.
