I gave this a shot but haven't had much luck with it. When I try
os.execlp I get an error saying unknown file or directory. Whether this
is in reference to Python or my script I don't know, however python is
in my system's path variable and I'm running the script from the dir it
is located in.
At someone else's suggestion I tried using a loader script with
os.spawnv using the os.P_WAIT flag. Unfortunatly this exits right away
(presumably never starting my server).
I also tried subprocess.Popen and then calling child.wait(). This sent
me into a loop of exceptions saying that the socket the server is
opening is already in use (even on the first try).
Does anyone know of a nice reliable app that already does this for you?
Open source preferably.

Noting that sys.exit() and possibly several other things can "raise
SystemExit" and while it is a subclass of Exception (and gets caught by
the above), it is usually considered a clean and intentional exit and
changing the above to do this is probably best:
os.execlp(.... etc etc
