A rather crude but working patch attached, applies on top of
patch-188.8.131.52-vs184.108.40.206.8.diff, didn't check other versions.
Other important problems (though not so trivially reproducible) are:
* (pty-related?) locking imbalance on vserver shutdown -- I don't
have logs handy but shutting down a vserver with a screen session
inside (screen on the host, running vserver enter) tends to cause "xid
exited with lock=-19" or something to that effect. The machine seems
to operate quite normally (apart from subsequent "vserver stop"s
hanging after killing all processes) but fails to reboot cleanly.
* strace'ing a guest process from the host sometimes makes the
machine go down in flames, but I have no logs or further details,
