Though not so elegant, it sounds workable in practise.

Support for CGROUP_ATTACH_PROCESS adds complexity and some subsystems
may have to aware of this and write code to support it, but fortunately
it seems only numtasks needs to deal with this. Or we can implement
this new task attachment framework for CGROUP_ATTACH_THREAD mode only,
to see how good it works, and later we add support for
