Just a semi-random warning for anybody as stupid as me: "finally:"
blocks do not handle exceptions, so don't expect things like using the
traceback module to work there:

try:
    main1()
finally:
    print exception_format(e)  # WRONG


I spent a long time tracing through the Python source code trying to
track down a non-existent bug in a C extension, thanks to this
misconception.  :-(
