    Description

      There appears to be a race condition in QThread, similar to the bug in task 163880. Given a QThread subclass with a destructor like

      ~Worker()

      { quit(); if (isRunning()) wait(); }

      then quit() can be called before the event loop is ever entered, and wait() will never return, leading to a deadlock.
