If the thread runner C function calls the pure virtual Run too early, before the constructor finished, it will crash. This patch delays thread creation and virtual function call to a separate startThread call. Thanks a lot to Jag for his help in finding the problem! r=jag git-svn-id: svn://10.0.0.236/trunk@193503 18797224-902f-48f8-a5cc-f745e15eee43
