You miss the traceback if you re-raise the exception. It produces this output:

$ python b.py
Traceback (most recent call last):
  File "b.py", line 17, in <module>
    raise e
Exception: f

Instead of this:

$ python a.py
Traceback (most recent call last):
  File "a.py", line 9, in <module>
    f()
  File "a.py", line 3, in f
    raise Exception("f")
Exception: f

When an exception is raised, traceback is taken from the current stack
unless a traceback object is provided to it. I'm using sys.exc_info()
to get the trackback of the original exception and using it when
re-raising the exception.

http://docs.python.org/reference/simple_stmts.html#raise

And there is no need to add "saved = e" as the exception is already
available as variable e.
