When dealing with debug logging, it's useful to track when an object's
construction is finished and it's now visible to the client. We can
detect this pretty easily by setting a flag the first time foo_to_handle
is called. As long as drivers only ever call that function at the end
of object construction (they all do to my knowledge), this should be a
reliable mechanism for detecting when a client knows about a handle.
