tor uses full cpu when unplugged

Hi. Here goes another stupid report of mine. I'm sorry:

When I unplug my network cord, tor starts using my full cpu. If I run service tor stop, it loops and never kills it. I have to kill it with a SIGPWR. I don't know if it's related, but I use wicd.

How do I debug this to provide useful information? If we can prevent disclosing my OS, that would be nice.
