That sounds right.  The only reason I didn't go that far was
because I wasn't sure if we wanted to allow shared sigacts
without leadership.  I think that it would be safest to require
userland to set either RFPROC or RFTHREAD.

Yes, the manpage is out of date.  What the hell is a sigact anyhow?
Can someone please fixup the manpage? :)
