As mentioned earlier: this is the only way to cleanup extension modules
in Python 2.x and the trash can patch broke this.

code (e.g. __del__ method) will fail running.

The dictionaries just contain simple Python types that don't
have __del__ methods, so deallocation works fine and it prevents
memory leaks when embedding the Python interpreter and restarting
it several times.
