Description Eric Roman 2009-01-15 18:32:02 PST
It doesn't seem like subresource loading is getting throttled, so if a script changes the 'src' attribute on an image repeatedly, it chews through memory and eventually crashes.

Test case will follow.

Causes unbounded memory growth

This test burns through memory (then crashes) in safari.

In IE7 and FF3, the memory consumption levels off.

This is also the cause of a significant Chromium memory leak and crash:  http://code.google.com/p/chromium/issues/detail?id=36142
