extensions: properly mark progress as part of core

This should have been done as part of or as an immediate follow-up to

# showstack.py - extension to dump a Python stack trace on signal

# binds to both SIGQUIT (Ctrl-\) and SIGINFO (Ctrl-T on BSDs)

    traceback.print_stack(args[1], limit=10, file=sys.stderr)
    sys.stderr.write("----\n")

    try:
        signal.signal(signal.SIGINFO, sigshow)
