I haven't had a chance to test this on the robot, but given the warnings around the SystemRestart exception ("This is still not all that reliable..."), I wonder if using Python's own reload() would be better?

This works on my local machine...any reason not to do something like this? Also, anyone have an idea how to improve it?

robot.py:

from my_exceptions import RestartException
import real_code

while True:
	try:
		reload(real_code)
		real_code.go()
	except RestartException:
		print "Reloading and restarting..."
		pass

my_exceptions.py:

class RestartException(Exception): pass

real_code.py:

from my_exceptions import RestartException

import sys,os,re,time

# decide if we need to reload based on some signal, in this case a file existing 
which we delete
# on the robot, this would be a joystick check
def check_restart():
	if os.path.exists("do_reload"):
		os.unlink("do_reload")
		raise RestartException

def go():
	while True:
		check_restart()
		print "Test."
		time.sleep(1)

With the above, if I have it running in one window, edit real_code.py, then create "do_reload", the real_code.py is reloaded and restarted at the next tick.
