Hmm.  I think a better solution would be to do something like print an
interpreter level traceback as far as the last opcode being executed,
and construct an app-level traceback from there on back (also,
stashing the interpreter level details away for later inspection, as
the half-hearted tb_server code does seems a good idea).

However, just commenting the printing of interpreter level tracebacks
out does seem to be a net win.

So change TODO :-)

Yes, the main.py/py.py/interactive.py refactoring is something that
has been a good idea for over a year, I think.  But what we have works
well enough so noone's gotten around to doing it.

A nice idea.
