Steve's code works even without "pushdisplay(TextDisplay(STDOUT))", which tells us that the problem of not seeing regular Julia console output on STDOUT may be because we don't read it properly. We may have to wait, close the write pipe, redirect the output back to the original... or something else, like printing something. Maybe, the "print(orig_STDOUT, s)" command does the trick? This should be easy to Julia experts, but drives newbies crazy.
