I don't see a need for resurrection here. Why can't it
create another object holding the necessary info for
doing the waiting?

Any subobjects which may need to be preserved can be
passed as arguments to the finalizer, which can then
prevent them from dying in the first place if it wants.

I'm far from convinced that there's ever a *need* for
resurrection.
