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?

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.
