'complete()' is supposed to be callable from interrupts, but the waiting ones aren't. But 'complete()' is all you should need to call from interrupts, so that's fine. So I think completions should work, if done right. That whole "make the parent wait for all the children to complete" is fine in that sense. And I'll happily take such an approach if my rwlock thing doesn't work.
