           Summary: Too many ScrollAnimators are allocated on pages with
                    frames
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bdakin at apple.com


Currently, ScrollableArea::scrollAnimator() will create a ScrollAnimator to return if m_scrollAnimator is null. Because of this, we end up creating a ScrollAnimator for nearly every frame on webpages. For example, we allocate 22 ScrollAnimators on  http://www.disboards.com/showthread.php?t=2512881 even though only the main document needs one.

Patch forthcoming.
