That's right.  It is not good to have a constraint that accepts
more than the predicate, since reload will at this point only
consider the constraint.  Adding a more restricted constraint
should be the proper fix for this problem.

You'll need to mark your new constraint as EXTRA_MEMORY_CONSTRAINT
so that reload knows what to do when an argument doesn't match.
