[mod_python] All spawned threads in Restricted Exection Mode

I tried some tests with different versions of Apache/Python/mod_python,
and narrowed it down to Python version 2.3.5 or later:

Apache/2.0.44 (Win32) mod_python/3.0.3 Python/2.2.3 - OK
Apache/2.0.53 (Win32) mod_python/3.1.3 Python/2.3.4 - OK
Apache/2.0.44 (Win32) mod_python/3.1.3 Python/2.3.5 - Fails
Apache/2.0.53 (Win32) mod_python/3.1.3 Python/2.3.5 - Fails
Apache/2.0.53 (Win32) mod_python/3.1.4 Python/2.4 - Fails

Looking for information to do with 2.3.5, I found that this bug has
already been logged:

http://sourceforge.net/tracker/index.php?func=detail&aid=1163563&group_id=5470&atid=105470

Not sure whether this is a Win32-only problem.

I'm going back to version 2.3.4 as I don't know enough about the
internals of python to fix this, and threads are useful things to have
working.

Thanks for your time,
