Re: How safe is this program?

I can't GUARANTEE anything, but no modules in the standard library
ever call sys.exit, and no internal malfunction will ever cause a zero
exit status. All errors that cause an unhandled exception will cause
a nonzero exit status. The (incredibly rare) fatal error also causes
a nonzero exit status. So you can be pretty confident that the
program only exits normally when you want it!
