I can't remember the bloke's name who wrote some patches, but AFAIK,
it's basically the same bug as the one triggered by the sleep 10 & stunt.

If I OpenSSH v2 to our RH loonucks boxes, and start a daemon
process (in this case, SNPd, but that's not relevant), I can 
then not disconnect.  ssh just hangs after I
attempt to log out.  As above, it's a known problem, I believe it's
fixed in -current, but I haven't had time to play with it yet to 
see if it is or not.

Not right now, but I can tomorrow.  It doesn't really matter, the
gist of my question is "are you planning a patch release anytime 
soon?".  If you're not, I'll go to the trouble to try and test 
the current snapshot, if you are, I'll wait and try it then, as
that'll be easier for me :)
