(after a core-dump of Python due to "bus error"). I can't seem
to get the core-dump off the box or I'd try to post it.

I hope this is better. Basically, I'm running a python
program that reads in fdisk information, and writes it
out. Attached is the python code... it works a few times,
but then eventually crashes. However, the general crashing
problem doesn't seem to be dependent on Python.
Best,
