IIRC, you must be careful when using Unix.fork in a gtk program,
because the child thread will attempt to close the X connection on exit,
except if you use exec to start another command.
The natural way to do it is indeed to start independent threads for
readers. Glib.Io.add_watch is another option, if you just intend to
wait for input without blocking computations.
