Couldn't you open /dev/tty for responses and still use stdin for data? A simple way of making input out of band

@RichHomolka less actually does open /dev/tty, but opening that device just gives the process another descriptor to the actual tty device, and with two descriptors to the same device, the reads would compete over the same queue of input characters.
