@end defun
@defvar redisplay-dont-pause
If this variable is @code{nil}, arriving input events preempt
redisplay; Emacs avoids starting a redisplay, and stops any redisplay
that is in progress, until the input has been processed. In
particular, @code{(redisplay)} returns @code{nil} without actually
redisplaying, if there is pending input.
The default value is @code{t}, which means that pending input does not
preempt redisplay.
@end defvar
@defvar redisplay-preemption-period
If @code{redisplay-dont-pause} is @code{nil}, this variable specifies
how many seconds Emacs waits between checks for new input during
redisplay; if input arrives during this interval, redisplay stops and
the input is processed. The default value is 0.1; if the value is
@code{nil}, Emacs does not check for input during redisplay.
This variable has no effect when @code{redisplay-dont-pause} is
non-@code{nil} (the default).
@end defvar
@defvar pre-redisplay-function
A function run just before redisplay. It is called with one argument,
the set of windows to redisplay.
