	It looks fine to me; I'll cherry-pick it.

	It -looks- like you do this on every startup, when in fact we really
only want to do it -before- we run 'exec' in this rather rare re-start
condition :-)

	Since max-fx can be quite large, and each syscall takes an appreciable
time most Linux spawn impl's go to the bother of opening /proc/fds,
parsing it and closing up to max-really-open-fd - which tends to be a
much smaller number :-) [ and all of this down to the uber-dumb default
of CLOEXEC that should never have been ].

	Ergo, I'd be happier if on master we only did this prior to the exec in
the unusual case. Really nice catch though !

	Thanks !

		Michael.
