I did some more tests:
At console 1:
host:~# vserver deb4 enter
deb4:/#
.. Then I stopped all services in deb4 ..
deb4:/# ps ax
PID TTY STAT TIME COMMAND

4999 ? S+ 0:00 login

At console 2:
host:~# vps ax|grep 8004

5023 8004 deb4 pts/0 Ss+ 0:00 /bin/bash -login

At console 1:

The same doesn't work with another vserver (deb3).
With deb3, I can stop all services, then after CTRL-D there is no deb3 anymore
