Yep, you'll need this around the whole script:

try:
  # the script
except:
  sys.exit(1)

If we were paranoid about segfaults which I've seen
happen with ctypes, one might wrap the script in (unlimit -c 0; )

Yep that should give enough test coverage,
and we can just comment in the script for cases where it fails.

cheers,
