To be honest, I don't recall much about this 6-monthes-old patch.

What I recall however is that it removed a significant size notably
because we don't integrate the python unittests *at all*. And they were
taking a significant space.

I'd say that this patch reduces drastically the size of the interpreter
without adding extra bugs (at least none that we caught so far). So
maybe we can just merge this patch, close the bug, and if someone's
willing to improve the situation, he can still step up and send
additional patches.
