     Easy: call pipe, then fdopen.
     
     But I suspect that you're planning to make the output go to a
     pipe which is then read by the same process?  That is likely to
     deadlock: the output module can fill up the pipe buffer and
     block.  Blocking goes on forever, because the GUI will never get
     a chance to read from it as it's in the same process.

Or we'd need to introduce some kind of concurrency.  Either through
multi-threading !! or by scheduling the output driver to give up
control if it would otherwise block.  I think one of these solutions
would be desireable in the long term; I wouldn't want the gui to
'hang' for 10 seconds because somebody executed a procedure which
caused the output driver to write 100MB of text.

But you're right.  For now, perhaps it's better not to go down that
path.
