Themeroller: Arbitrary performance or 404/timeout issues

[jzaefferer]

​http://ui-dev.jquery.com/themeroller/ works (icons are there), but takes a looong time to load. If it loads at all, got two timeouts out of four requests.

According to Firebug's netpanel, this took 40s to load on one request, ending with a timeout: ​http://ui-dev.jquery.com/themeroller/images/themeGallery/theme_90_ui_light.png

There is an image that results in a 404: ​http://static.jquery.com/ui/themeroller/app_css/images/ui-bg_glass_55_fbf9ee_1x400.png Referer is ​http://static.jquery.com/ui/themeroller/app_css/app_screen.css

Switching preset themes works, but can take a long time, mostly on images.
