context.py errors

It looks like a couple of the handleXEvent functions in there use event.killer_pid on events that dont have that attribute. Curious if theres a reason for that, or if its an oversight from copy-pasting functions.

Traceback (most recent call last):

I'll submit a PR to fix if its not intended
