           Summary: [Qt] QtInstance method cache ownership rules are
                    unclear
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: oliver at apple.com


I've temporarily made a cache use Global<> however it may be possible to make that produce ref cycles.

I'm also unsure how correct the method cache is -- if more than one JS object uses the same backing instance the two objects may share function instances.  I don't know if this is possible, or even desired, just recording the observation.
