does python have useless destructors?

Code relying on destructors being run is not "broken", it is "relying
on implementation of CPython". Those are two different things.

Hopefully, at some point, destruction semantic will find its way into
the language itself and then Jython will either have reference
counting or be "broken" ;-)

In my very personal and definitely biased opinion, getting working
destructors is more important than maintaining compatibility with
Jython (although I hope achieving *both* is possible). YMMV.
