Just in case you missed the answer I gave earlier...

I don't even want this behaviour all the time with the same
script because end-users will be confused if they get dropped
into pdb.  Believe me, you don't want to explain what pdb is
to people who have a hard time even navigating via the
command prompt!

The best situation would be to be able to invoke this behaviour
only when I want it (i.e. during coding/debugging) and not have
to change anything (including sitecustomize.py) when I don't
want it around (the same machine might be used by both the
developer and the end-user).

Essentially, I believe this means being able to invoke the
script from within pdb and getting pdb to remain in itself
in case of an unanticipated exception (is that too much to ask?
:-D)  I want to be able to use pdb like other debuggers, i.e.
it's only active when I call a program under it, and also behave
like other debuggers which do not exit if an error occurs.
