After logging in to the WOW Account Management Area, the latest build begins to render the page. It gets to the point of "Loading...120 of 125" and then sits there, the address/tab bars showing that it is still attempting to load. WebKit must be force quit at this point. Once it begins loading the page WebKit goes from <1% CPU to consuming an entire processor core (Core 2 Duo), and memory jumps from about 30MB to over 150MB within a few seconds, and then steadly climbs (more slowly) from there. - The error does not occur in the Tiger-shipped WebKit that standard Safari uses (on my machine: v2.0.4 (419.3)). - No Console output. - Reproducible with the last few nightly builds (retrieved via NightShift.app).

Disabling JavaScript eliminates the lockup. The main content loads fine, though the side (sitewide) navigation and some other peripheral elements do not load without JavaScript.
