Jquery.find in event.handlers is much slower than old quickIs

http://jsperf.com/jquery-1-7-2-quickis-vs-jquery-1-9-1-find

With jquery 1.9.1 scroll on ios becomes very laggy because of event handlers of touchstart and touchmove bounded to document.body. Patching jquery with old quickIs resolve this problem.
Is it possible to return quickIs in addition to current mechanic?
