Eric, does mentioning the reasons similar to those in my original description
for this bug seem fine with you?

Basically, the active code path with memoryCacheClientCallsEnabled == true
creates duplicate resource IDs for cached resources that are loaded in a way
similar to "(new Image()).src = 'foo.png'" (I'm afraid to touch the solid
ground of this behavior as it stems from the JavaScript VM handling DOM, but it
seems Safari will exhibit the same bug as Chromium, without disabling the
AforeMentionedCalls.)
