iPad/iPhone browser crashing when loading images in Javascript
I'm trying to build an image gallery in Safari that mimics the iPad photo app. It works perfectly, except that once I load more than 6MB or so worth of images either by adding them to the DOM or creating new Image objects, new images either stop loading or the browser crashes. This problem is widespread enough (with everyone else hitting up against the same limit) that I've ruled out my Javascript code as the culprit.
 
Given that you can stream much more than a few MB in a <video> element or through the in-browser media player, this limit seems unnecessary, and there should be some kind of workaround available. Perhaps by freeing up memory or something else.
 
I also came across this [reference for UIWebView][1].

"JavaScript allocations are also limited to 10 MB. Safari raises an exception if you exceed this limit on the total memory allocation for JavaScript."

Which matches what I'm seeing fairly well. Is it possible to deallocate objects in Javascript, or does Safari/UIWebView keep a running total and never lets go? Alternately, is there any workaround to load in data another way that doesn't eat up this 10MB?
