Comment(by ddrake):
I was going to reopen this ticket, but instead I'll leave this comment as
warning to anyone else trying to use this:
If you do {{{sys.exit(0)}}} in a Sage script, because of preparsing, you
effectively get {{{sys.exit(Integer(0))}}}, which results in the script
exiting with code 1! This is not what anyone would expect! This is because
of [http://docs.python.org/library/sys.html#sys.exit how sys.exit works]
when given non-Python-integer arguments. To make sure that you get the
desired behavior, use {{{int}}} inside the call to get a Python integer:
{{{sys.exit(int(2))}}} or whatever.
