web page with 5000-button form

WebKit 93384 loads about 70 button elements per second, so a page containing a form with 5000 button elements requires about 75 seconds to load and be ready for navigation. By comparison, Firefox requires under 2 seconds for the same page.

WebKits in Safari up through version 5.0 were as fast as other browsers on such pages.

Attachment is a simplified example of such a page. The real-world page that made this bug evident to me is at the above URL.
