(Whiteboard: [Perf])

The test page quoted loads between 53 and 555 stylesheets, depending on how the @imports are treated. The style system currently thinks "Hmm! Lovely! Lets download all 555 stylesheets!". However, since actually most of them are imported multiple times, the system could just download 53 and reuse the classes already in memory. A copy-on-write scheme for stylesheets that are reimported from other stylesheets would be very beneficial for performance. This bug will probably be fixed by Peter's forthcoming stylesheet manager class. Related bugs: bug 2029, bug 2765, bug 3421, bug 4529.
