def _key_is_empty(key, decl_class_registry, test):

test if a key is empty of a certain object.

used for unit tests against the registry to see if garbage collection is working.

"test" is a callable that will be passed an object should return True if the given object is the one we were looking for.

We can't pass the actual object itself b.c. this is for testing garbage collection; the caller will have to have removed references to the object itself.
