I have also had this problem with a long running process serving a lot
of stuff. I had to kill it in the end. If this was originally caused
by my code then it seems that the killthread code doesn't work
correctly, it shouldn't crash out? I've seen a similar issue with
windmill and killthread, both possibly using that same code from the
web, or using it in the wrong way etc?
