Capturing output from SPAWN [message #11565]

I would like to capture the output from a data-intensive
program invoked via SPAWN, but (here's the catch) I would
also like to have the program echo its output to the screen.

I've tried using something like this:

spawn,my_binary + ' | tee '+tempfile
spawn,'cat '+tempfile,output

But the problem here, I think, is that the pipe buffers
the output to the screen, and I don't see the output
at the same time it's produced by the binary.

Does anybody know of a way to capture the output AND
see it printed, unbuffered, to the screen?
