Without fail, after four or five successful runs of VPython scripts my
system experiences file system corruption.

I believe I am a victim of this bug on Ubuntu
9.10<https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/474928>,
which is indeed related to the dreaded Radeon Mobility 7500 graphics
adapter.  Dreaded because this thing has way more than its share of
problems, and ATI has set it adrift... no more driver updates...

I report this because someone else might suffer from it, and come looking
here for help.
