window-update-cursor

Hi,

I am trying to simulate a cursor with any size by using the generic 
function WINDOW-UPDATE-CURSOR, but the result is unsatisfactory,
that is, flicker, even though a double-buffer way has been used.
I checked the MCL manual "The generic function WINDOW-UPDATE-CURSOR
is called by UPDATE-CURSOR that is called periodically by the global
event-handling system."  I am wondering how the event-handling system
calls the function periodically, one third second or others.

By the way, do you know other ways to do that?  Thanks.
