<pre>As I recall, we were originally using PtrHash for this purpose (or a similar one in WebCore?) and Gavin changed to use the string hash instead to get a measurable performance boost. But I don’t think the change was to recompute a string hash each time; our strings memoize the result of the string hash function.</pre>
