this patch works but only because it ends up setting kintr always :-)
(keyrec is IOREC * not IOREC).  also i looked where repeat is done:
before evnt_timer is called.  so i think this is a better place:

 sorry,

PS: to get rid of a bad patch just feed it thru patch again, it will ask
if it should `un-patch'...
