Initial page loads fine, but refreshes or clicking on links (either into new window, new tab, or same tab/window) hangs for several seconds with one CPU core spiked to 100% utilization. Browser is unresponsive until the page eventually loads.
Snippet from Activity Monitor sample reports majority of time spent in:
WebCore::JSNodeList::getValueProperty(KJS::ExecState*, int) const
Can you please attach the entire "sample" output?

Activity Monitor sampling output during hang
I can reproduce this by reloading <http://nightly.webkit.org/start/trunk/142133> three times. On the third time I get a blank page.
It seems to happen on some sites with JS + DHTML.
The only way to fix it is to quit and re-launch webkit. Closing tabs and re-opening them does not fix the problem. Once a page stops loading, it never loads again until quit+relaunch.
Version 6.0.2 (8536.26.17, 537+) Mac OS X 10.8.2.
There is a new bug filed about reloading <http://nightly.webkit.org/start/trunk/142133> three times. I think that we should close this old bug to avoid confusion. I cannot reproduce with Safari 6.0.2.
I agree. The new bug URL is https://bugs.webkit.org/show_bug.cgi?id=109249 for those interested. The bug detailed in 19420 is different.
