In the days of the TTY a single user UNIX would give priority to keybaord interrupts, and in the return from the interrupt the scheduler would let the process blocked waiting for the keystroke (an editor perhaps) wake up and process the input.
Those days are long gone. By the time the Consent Decree let UNIX source be available and ported to the early 16-bit micros UNIX was already doing a lot of multi-tasking.
