Interesting data point there - that you actually have it handy and
choose not to use it. It's clearly designed for interactive mode, as
it assumes that it can restart entire blocks of code:

>>> for x in (1,2,3):
...  print x
...  if x==2: print os.pathsep
...
1
2
autoloading os
1
2
:
3

But that's about as good a "now go try this again" as will ever be
achieved with sys.excepthook, I expect.
