BTW, I don't think this would solve my problem as tail -f would block 
waiting for more data, as would prog2, so after prog1 finishes writing 
data they would block indefinitely on input. I forgot to mention this 
was supposed to be a short-lived pipeline, not daemons, as you had 
probably thought.

Also, I've already learned how to use misc/buffer correctly so the 
problem's gone. Thank you for your time.
