Any chance you have got sensible results out of popen to read and write
to another program? I've got some python code I'd like to run (and maybe
translate to ruby one day, but for now) and I can't get anything useful
out of popen("program", "rw") in shoes. I've done it in ruby before now,
but it stops the GUI dead. I suspect I'll have to use Threads and a Mutex.
Those are never fun to debug.
