Sizzle maybe slowing down DOM manipulations


Hello,
I haven't read the whole Sizzle code but I think the cache
functionality can really slow down all DOM manipulations.
I'm talking about attaching handlers to DOMAttrModified,
DOMNodeInserted and DOMNodeRemoved events. From my previous talks with
Dave Hyatt, he was saying that browsers have a way to never trigger
these events if no one is attached to them. Attaching an handler, even
small, could have huge performance implications.
I haven't run any test or benchmark but I believe you have tools for
that. Have you seen any performance regression after landing Sizzle
into jQuery ? This would only be visible on Firefox and Opera since
they are the only browsers to implement these events.
