Bobby, can we find somebody to work on it?  Simply blocking our test already.

Paul showed me two devices with the symptom today, both of them do not have homescreen process. I think that's why it "hangs", and it seems there're memory leaks, will check about:memory report.

I see leaks like bug 1183848 from the report. Paul, could you please try the patch there?
