It's a bit messy. If you do this:

kill `cat /var/lib/dibbler/server.pid'
dibbler-server start

You'd get a race condition. kill command returns immediately and the
server may take around 2 seconds to shut down. If you try to start
another instance immediately, it will fail at some point.

That's why the stop command was implemented. It sends the signal and
then is supposed to wait for the process to terminate and then exit.

Unfortunately, this code has a bug. Fortunately, it has been fixed
recently :)

Jean-Jacques was kind enough to provide a patch for this, which has been
accepted. I've merged it to git today. Can you try if the latest git
code works for you? I can't verify it myself, because it always worked
on my box and never had any issues. If you're interested in details, the
bug for this issue is #268
(http://klub.com.pl/bugzilla3/show_bug.cgi?id=268). If this fixes your
problem, make sure you say so in the bug comment.
