Should really follow up to this...

Actually, I don't think set -m was ever mended; I think it's always
been a bit of an afterthought that sets up a process group, but
doesn't do a lot else.  I'd be inclined not to worry about
side effects of this patch unless there's something demonstrably
worse, since it's fixing something you would expect to work
(and that doesn't depend on zsh wizardry).
