Actually, that wont work if zsh is the shell started by os.system() to start
the xterm (since the argument has a shell-meta-character, '&'), or if the
environment variable gets overwritten by the standard shell (like bash, on
most linux systems.)

To avoid that, you either have to do the fork() & exec() yourself, or start
the shell explicitly:

os.system("/bin/zsh -f -c 'xterm zsh -f &'")


os.system("/bin/bash -norc -c 'xterm bash -norc &'")

The best solution is probably to remove the explicit setting of the variable
in your .zshrc, and replace it with a conditional (only set it if it isn't
already set.)
