So some kind of guaranteed finalization would do the job, if one could
indicate that a particular object had to be collected when out of
scope. In fact, just having the ability to force __gc for such objects
would allow for a custom scheme, not so?

Whether this would impact on general performance, I don't know: such
objects would have to be specially marked for 'impatient disposal'.
RAII is the obvious goal for such a feature.
