Hi Peter,
It seems the problem is worse, the attach twice issue can happen not only as
Vincent raised when task moves between groups, but also when switching to fair
class. In addition, for newly forked task, the detach and attach also have
problems.
Thanks a lot to Vincent. This new version mainly addresses his comments to
reword the description of the problem.
Thanks,
Yuyang
