Take the space bank for example. It returns a key in key0. It uses the returner to
make the return. If the returner is returning to the resume key in key0, another slot
has to have the key to be returned.

Or do you propose to change everything that returns a key to skip key0 and start with
key1? That would be a bigger change. And I thought the whole point was that IDL
doesn't like to skip a slot.
