I've been trying to think of a way to do that. AFAICS the only way to
do that reliably would be to move the call to cgroup_fork() that hooks
into the parent's cgroup inside the lock on the group leader's thread
list, and move the fork callbacks into cgroup_fork(). (Which would
mean that they'd not be able to sleep/fail, etc).
