IOError: [Errno 2] No such file or directory '/tmp/fileag3TSg'
Uhh, what? What file? Why are you even looking there? What were you

Failed to open scratch file '/tmp/fileag3TSg' (something deleted it in mid-run?) at moo line x.
Ah, I need to kill tmpreaper. This error is useful.
Generic exception handlers *suck*.
