Paring down our script, it appears that the root of the problem may be 
that we're doing some funky termios stuff in the script after launching 
rabbit, to let us do character-by-character input polling on that script 
(in the service of "press Q to quit"). If I launch rmq in such a way that 
it doesn't share stdout with the script, there's no problem.
