Thanks.  I am still concerned about the group task exit issue you saw in
v2 and how count could be out of sync with the mm struct map count.  I
wonder if it was this set or something else that was in linux-next at
the time of your testing.

Were you closing a window in firefox when that happened?  Maybe I can
attempt to recreate the issue again.
