Force queue, if locked. This will set the RunLevel
This can be called in AsyncCAll (TApplication), while in QueueExecuteLock (this does not run on unlock)
Without ForceQueue, the queue is virtually locked until the current command finishes.
But ExecCommand must be able to unlock
Reproduce: Trigger Exception in app startup (lfm loading). Stack is not searched.
