xidlehook check might be out of date
I have installed xidlehook in arch linux via AUR and it seems as though the comment here: https://github.com/quantopian/PenguinDome/blob/master/client/plugins/screenlock.py#L125 reflects a perhaps-out-of-date version of xidlehook.
My usage of xidlehook only uses a duration, command and canceller:
--timer <duration> <command> <canceller>
@epchris can you test the branch referenced in the PR above to see if it fixes this for you? @irlevesque if you are still using the older version of xidlehook which uses the old syntax, can you test to confirm that this change works for you as well?
@jikamens I no longer use xidlehook so I'm sorry I can't test the behavior.
