For completeness here's what has worked for me, as hijacked from ka-map:
var timer=null, delay=2000;
var paused=false;
function mousePaused(e) {
var coord = map.getLonLatFromViewPortPx(e.xy);
... do something with the coordinate ...
}
function mouseMove(e) {
if(timer) clearTimeout(timer);
if(paused == false)
self.timer = setTimeout(function(){clearTimeout(timer); paused = true;
mousePaused(e); paused=false;}, delay);
}
function mouseOut(e) {
clearTimeout(timer);
}
and in the onload function...
map.events.register("mousemove", map, mouseMove);
map.events.register("mouseout", map, mouseOut);
I can file a ticket if that would help.

We could cook up a pause handler pretty easily. This would let you
develop controls that respond to mouse pauses. The reason to use a
handler for this is so that it can be used in multiple controls - or can
be used to set the behavior of a control that might respond to clicks by
default. For example, an Information control (requests GetFeatureInfo
by default) might use a click handler by default (responding to single
or double-clicks) - giving this control a pause handler instead of a
click handler would change it's behavior to respond to mouse pauses
instead of mouse clicks. No code floating around yet for this, but it
shouldn't be hard to write.
A ticket would be the first step. Then a patch.
