I do something similar by overriding retrieve, and there's one on the
wiki that uses triggers.  I think these solutions are okay, but one of
them should be built in.

I realized that my sample case, where search is fast but fetching
objects is slow, was an anomaly.  For most people, search is the slow
part.

That does a select and then a delete for each row returned.  Which
brings up another major feature request:

- More efficient SQL for Class->delete() and
Class->search()->delete_all().  Performance matters a lot to most users.

And while I'm at it, support for multi-column foreign keys.  I hand-code
these at the moment.
