Comment 9 for bug 481512

Hm, the cores don't show anything that would help me. I went by the thread listing from the second paste in the current bug description. That shows "reopen" and "emit" colliding and I have added locking to prevent that. (emit already did it but reopen didn't). That fix will be in the next deploy and we should watch if it helps. Otherwise we may have been looking in the wrong direction.
