The current design is that it's not supposed to happen - drivers that
aren't going to attach are theoretically supposed to know this and not
match. This is intended for the case when there's another
lower-priority candidate driver that should be given a chance.

For a lot of circumstances this isn't very realistic and there's been
talk of changing the model, but no agreement.
