D'oh. This is a hard problem, especially the part of it that involves
handling detach, so I wouldn't feel too bad about that. However, to
beat this possibly-dead horse a little more, I think you made the
error of writing a patch that (1) tried to solve too many problems at
once and (2) didn't seem to really have a clear, well-considered idea
about what the semantics ought to be.
This is not intended as an attack; I want to work with you to solve
the problem, not have a fight about it.
