I remember how this used to be a common problem with web ads in the mid 2000s.

One of the reasons why I loved Chrome when it came out was that the multi-process architecture made it easy to kill a Chrome process without closing all my open tabs: The offending tag would "crash," but otherwise I could continue browsing.

Also, around that time there was an ad on Slashdot that gobbled CPU. I remember quickly figuring out that it was the ad, grabbing a screenshot, and emailing them. I got back a quick knowledgeable reply (and apology).
