On my Mac I ran Shark on Safari and got the following functions as top of the profile:
13.0% WebCore WebCore::CSSStyleSelector::SelectorChecker::checkSelector(...)
10.8% WebCore WebCore::CSSStyleSelector::SelectorChecker::checkOneSelector(...)
2.6% WebCore WebCore::RenderLayer::paintLayer(...)

I cannot reproduce this bug on Mac OS X with WebKit nightly build r46126. Which version of WebKit did you test with in Safari? That's an incredibly important detail to include when filing a bug report.
Ivan Posva
I ran this on a released Safari 4.0.x. Where x is less than 2, I can't tell the exact version as I since upgraded to 4.0.2.

Does it still reproduce with a tip of tree build of WebKit for you? If not, this bug should be closed.
Alexey Proskuryakov
FWIW, I cannot reproduce this even with Safari 4.0.1.

It looks like they fixed their CSS as it no longer repros.
