Comment 48 for bug 515138

This may be related to something in power manager and or power profile switching. I've noticed that when I unplug/replug the power adapter for my laptop, I end up with 2 new zombies, 1 for the unplug, 1 for the replug. If I have some time I'll dig into this deeper, but figured I'd note it here as this seems to be an on going issue (at least for me)
