I guess i found a possible answer to my problem: The jail is running
mldonkey, which is started via /etc/rc.conf. If I don't start it, the
jail comes up as expected. These are the last two processes spawned in
the jail:

37947  p3  T+J    0:00.01 su -l mldonkey -c /bin/sh -c
^I"/usr/local/bin/mlnet ^I ^I ^I>> /dev/null 2>&1 &"
37948  p3  TJ     0:00.01 -su -c /bin/sh -c ^I"/usr/local/bin/mlnet ^I
^I ^I>> /dev/null 2>&1 &" (zsh)

It's suspicious that there are ^I's in there. And as a side-note:
Other jails have the same problem, with completely different services
to start up.

What to do about it? If I start mldonkey manually when the jail came
up, it works as expected, but this is really suboptimal...
