Almost the same commit as me in de7df26 (not yet in a PR, so feel free to merge this instead).
I think the only place logic differs from mine is in VSuspense where I think we can get away with pretending the detached_parent always detaches.

Looks good to me.

Just wondering, when is true passed to detach? I see the false being passed almost everywhere.
