           Summary: [v8] get rid of unnecessary synchronization in weak
                    reference callbacks
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: antonm at chromium.org

Currently browser and renderer execute V8-related code (including GC) in the
main thread.  So a lot of synchronization is actually unused and only makes us
slower.

I don't do the full cleanup (but would do on request) to make it easier to
rollback this synchronization infrastructure if need be.  On the other side
that's exactly what version control should do.
