The fact that it's bad already or that there's worse out there is no excuse.

Right (I'd expect that function to take the whole list, BTW, but
if mapc can be used, it's not critical).

Of course, with only 2 users so far, it might be tricky to decide what
is "common".

I don't see why sorting would be needed.

Clearly, the returned list does not need to give an action for
all frames.  Only for those which we did consider.  So we don't need to
call `frames-list' just so as to build the return value.

I think it's cleaner.
