Comment 5 for bug 1021696

I can't seem to reproduce this exactly, `kill -TERM pid` will exit gerritbot and delete the pid file. Interestingly using any other signal will exit gerritbot but leave the pid file, I'm thinking its probably due to an uncaught exception. Pip freeze lists the following notable package versions in my virtualenv:

gerritbot==0.2.0.1.g6208bd9
gerritlib==0.4.0
irc==8.9.1
lockfile==0.9.1
python-daemon==1.6
