We could change the make_dev_credv() routine to crcopy() everything
except the prison when we're creating a node in a jail. The following
patch fixes the zombie jail bug on my machine:

Could other people experiencing this problem as well give this patch a
try? Thanks a lot!

Does this behavior still occur if you set sysctl kern.pts.enable=1 ?
Is this at all related to why I have been experiencing zombies left behind
for any process that alloc's its own tty (such as gnome-terminal [actually
gnome-pty-helper])? If I CTRL-D to end a gnome-terminal session, it will
hang all of the gnome-terminals I have open and I typically have to reboot
to clear out the zombies that remain. I can't open any more apps that use
gnome-pty-helper to allocate ttys unless I attempt to kill it and start it
anew (and I am not even completely sure if that works).
