1- PENDING_OUTPUT_COUNT is not a feature, but an internal
       implementation trick.  Not sure what is the corresponding feature.

If you type a character during redisplay, it preempts output.
But all the characters that are buffered have to come out on the terminal
before it really succeeds in preempting.

The feature which PENDING_OUTPUT_COUNT is used for
is to limit the amount of output that gets buffered,
so that preemption is snappy.
