Ahhh, well considering this is me SSH'ing in, one would be the child fork(), 
the other the main server, i would say.

I've looked more, and it deffinatly only does it whenever the mysql-server is 
under heavy load. if the query takes ~ < 0.10s, then it seems to work, 
otherwise, i get this when logging in:

[theo]~# ssh address@hidden
Connection to shell-server closed by remote host.
Connection to shell-server closed.

sometimes it gets as far as logging me in and showing an motd:

[theo]~# ssh address@hidden

[snip legal crap in motd]

address@hidden:~$ Connection to shell-server closed by remote host.
Connection to shell-server closed.

that mostly seems to happen when nscd is running.

arghghgh!
