Checked the patch: it fixes the problem. Thanks.

Will this go into Python 2.7.5 ?

I'm asking because we need to issue a patch level release of egenix-mx-base and if Python 2.7.5 will fix the problem, we'll just add the work-around for Python 2.7.4.

Regarding a better cleanup logic: This is available in Python 3.x with the new module init logic and we'll use it there.

PS: The approach with doing the cleanup at module startup time won't work, because the still existing objects will reference parts of the already cleaned up interpreter instance.
