I'm pretty sure that should be os._exit(0)

This is now the child process.

I think that's changing Python's idea of stdin etc but not the
operating system's idea of them. You won't be closing the original
file descriptors, and if you run any subprocesses they will end up
with the original stdin/out/err. Unless sys.stdin is more magic
than I'm aware of.
