Emacs redisplay normally stops if input arrives, and does not happen
at all if input is available before it starts. Most of the time, this
is exactly what you want. However, you can prevent preemption by
binding @code{redisplay-dont-pause} to a non-@code{nil} value.
@defvar redisplay-dont-pause
If this variable is non-@code{nil}, pending input does not
prevent or halt redisplay; redisplay occurs, and finishes,
regardless of whether input is available.

** The default value of redisplay-dont-change is now t
This makes Emacs feel more responsive to editing commands that arrive
at high rate, e.g. if you lean on some key, because stopping redisplay
in the middle (when this variable is nil) forces more expensive
updates later on, and Emacs appears to be unable to keep up.
