           Summary: Math.random repeats values in different workers
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: webkit at catchall.getdown.org


When calling Math.random() in different workers, Math.random() is returning the
same values in the same order in each worker. 

For example, when executing the following code (in an object) in webkit in
multiple workers, the object's redness is set to the same value in each worker:
    this.redness = Math.round(255*Math.random());

I do not have this problem in Chrome or in Firefox.
