[Bf-python] Blender, Python, and Irix

[Chris Want]

Blender has been extremely unstable on Irix
for a while now, and it seems that the problem
is related to python. I thought that the problem
might have arisen from the transition from
python 2.2 to python 2.3, but I hacked blender
to link with python 2.2 again and it doesn't fix
the problems. Most of the problems are unpredictable
and hard to diagnose, but scriplinks appear to cause
a lot of the problems. One problem that is fairly
easy to reproduce is that blender seems to always
crash when closing the application. Here is a
backtrace:

I hope this is enough information to point to something
obvious... if not, I'll have to remove python support for
the irix build.
