The arrival of subprocess output causes the pselect call to return,
marking the file descriptor for that process ready to be read. Emacs
then reads from the descriptor, and returns to the idle loop. If by
that time no additional process output arrived, Emacs will enter
redisplay.
IOW, arrival of process output is an event that causes the main loop
to crank one more time, and that includes redisplay.
