However, while a particular thread is executing actions and another thread attempts to start executing actions for the same symbol, it will bail out and end up marking the symbol event as complete, corrupting the state tracking for actions currently being executed on the other thread. Fix is to ensure that we attempt to mark the event as complete only if there are no pending actions being executed for the event.\r\n\r\nFixes VSO Watson
