The actual reported problem was likely because of known issues with running subversion Python wrappers in a sub interpreter.

The rest of the conversation was for a completely different issue which relates to mod_python not using thread APIs in Python in the required manner.

In both cases it is a package distinct from Python itself.

The only fault in Python is the inadequate documentation describing the intricacies of using threading APIs in Python, especially in relation to sub interpreters and also user created thread state objects against main interpreter.

As far as the original issue is concerned however, issue should be able to be closed.
