It seems that some resources leak.
I will make further investigations.

Zhu,
I suspect this is an older error. I traced all the add and drop ref
calls for PDs, then ran the full suite of Python tests and also test_mr
which includes the memory window tests by itself and then counted the
adds and drops. For test_mr alone I get 85 adds and 85 drops but when I
run the whole suite I get 384 adds and 380 drops. Since the memory
window code is only exercised in test_mr I think it is OK. Somewhere
else there are missing drops. I will try to isolate them.
