[Bug 1300722] Re: hud-service is eating up 100% of one of my CPUs in a poll loop
Here's my system log spanning the time when the bug occurred. The log
starts around the time when I used System Updater while playing chess,
and ends at the place where I rebooted. I don't understand why there
were so many thread creations owned by 1000 ... is that the symptom of
this bug?
