I've fixed two of the leaks.

I think I'll try that, but this will take ages to run. Meanwhile
here is the result of my patch for the complete test suite:

(This includes only unittest based tests)

It would simplify hunting leaks if we separated tests that are
known to change the total refcount from the rest by moving
them to separate test methods or even test cases.
