           Summary: DOM URL is flaky when workers are used
           Product: WebKit
           Version: 420+
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.jensen at digia.com


When the DOM URL Constructor is used in both a main thread and a worker thread, the results becomes unstable. Specifically the methods will be likely to become undefined in one of the contexts (for JSC in V8 it seems to crash).

The reason seems to be that HashTable::createTable in Lookup.h registers the method names, only in the current context, once another context accesses the same table, it will be unable to lookup the identifiers used to access the methods.
