[Bug 1494479] [NEW] initctl stuck taking 100% CPU on "emit xsession"

 

Public bug reported:

I noticed a battery drain on my mako OTA6 recently.  Looking at the
Terminal app, initctl was taking 100% CPU.  It wasn't slowing down my
general experience like bug 1480877 does, because dbus wasn't affected.
It was just draining the battery.

The specific initctl line was:

initctl emit xsession SESSION=ubuntu-touch SESSIONTYPE=

It never seemed to die.  Had been running for 669 minutes already.
Can't find the logs for initctl (where does it put it's output?).
