If I find events are queuing up I just set a flag in the routine that's taking the time
and ignore any events that call it until the flag's unset again. ie, something like
routine: does [
view layout [
... feel [engage: func [face action event] [
if all [action = '... not processing][routine]
Obviously you shouldn't skip events like key-presses where users are typing in text,
but for ones you can skip it usually works quite well.
