Start debugger automatically, with no breakpoints?

Question

My application has debug = True configuration option which turns on many facilities useful for debugging. I figured that it would be a nice idea to enable the debugger when debug mode is turned on, but not the way python -m pdb someapp works. Instead, I'd like it to behave as if the user entered "cont" right at the startup, so that the debugger appears only when an exception was caught. How do I do that on the source code level?

import sys

def run_pdb_hook(*args, **kwargs):
    import pdb, traceback
    traceback.print_exception(*args, **kwargs)
    pdb.pm()

if debug:
    sys.excepthook = run_pdb_hook
