Don't just use sys.exit use a try/except SystemExit...
>>> import sys
>>> try:
...    sys.exit()
... except SystemExit:
...    print 'caught exit'
...    raise
...
caught exit

However thats usually the wrong way to do it.
Better to have your program exit naturally and have the control logic 
in
the code control when it finishes.

HTH,
