# The system function may need to be modified so that external programs that expect to be running in a terminal will continue to work properly. On Unixy systems, this job can be done with ptys. I guess Windows systems can use a hidden console? But if these things are required, are we more or less back to were we were before since we used a pty and hidden console to implement the terminal widgets? I believe the Emacs start-process function must do similar things, so we might be able to reuse that code.
