That is sad. (And, I am only slightly ashamed to admit it, quite
funny.) But on the other hand, quite impressive that it didn't bomb
anywhere!

Whenever I'm about to do something really dangerous, I like to first
open an SSH session from another computer - bash running inside there
can usually kill any process fairly efficiently, without need for UI
interaction. Failing that, good ol' Ctrl-Alt-F1 to get to a console is
usually the next best, but sometimes logging in requires a lot of
resources.

This is actually one place where I'm really glad Python doesn't do
much with multiple threads (for instance, it won't gc on another
thread). A dual core CPU keeps everything happy!
