           Summary: Some long-running JS does not get detected as "Slow
                    Script" and stopped.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dimich at chromium.org

The long-running script should be aborted with a "Slow Script" dialog.

But sometimes, this dialog does not appear and the script is not aborted -
instead the browser just hangs.

Url that hangs:
javascript:function fib(i) { return i < 2 ? 0 : fib(i - 1) + fib(i - 2) + 1;};
fib(60);

Url that popups the right dialog as expected:
javascript:while(true) {};
