When using Ajax to retrieve a large file (70k) and using .html to load the message into a div, the system memory continues to climb. Simply run the attached test.html which loads the ipsum2.html file every 20 seconds and watch the memory usage of IE grow. I am using IE6 but have tested this on IE7 and FF3 with the same results. I ahve also attached a screen shot of sIEve that shows the growth. The drop between is when I removed the .empty() call.
