           Summary: Extremely slow parsing of deeply nested divs
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: shadow2531 at gmail.com

WebKit-SVN-r34278 with Safari Win32 3.1.1(525.17)

Parsing ~15840 divs deep takes a long time in Webkit.

On a PIII 733MHz, Opera 9.5 (latest snapshot) and FF3 (latest trunk) take
around 1.5 to 2 seconds to parse.  Webkit takes ~66 seconds.

Seems like there's room for optimization.

Will attach example.
