Seeing a comment in the code about switching out the loadingBay implementation from a hidden div to a document fragment, I tried it out, and it was pretty quick. Haven't been able to do a benchmark, but I have been able to do a bit of browser testing - works in IE8, IE7 compatibility mode, Chrome, Firefox. Document Fragment should work in everything including IE6, according to Resig.
