You could package your program into a function or class and just
restart that.

[code]
# global flag for restart.
do_restart = False

def main(args=None):
    # program code
    # set do_restart and return to restart

if __name__ == "__main__":
    retval = main()
    while do_restart:
        retval = main()
    sys.exit(retval)

[/code]
