If user input never stops, redisplay will never happen (except if
Emacs needs to display an urgent message or something).

And we cannot really inhibit (i.e. pause) redisplay, because
processing user input usually changes buffers' contents, and so the
data structures built by the interrupted redisplay no longer reflect
what's in the buffers.  Thus, redisplay must start anew.
