it is for debouncing.
that is, when we get a zillion window resize events per
second (which can happen with some window managers),
we do not want to flood that to the remote side as it
is a very expensive operation in devdraw model,
as every graphical program needs to be notified
and re allocate a its screen and then redraw.
so with the sleep, we limit the rate of devdraw
resize to once per second.
also note the location of the delay. it will do the
first resize *immediately*. but then wait at least
a second until we check if it got resized again.
so this is only affecting window managers that
continuously generate resize events for the window.
