   > step-5 ( High light ): If the meta ledger needs to be created, create ledger will be triggered first and the current request will be put into the pending requests queue. It is possible that step 4 has been completed before the request is put into the queue, so this request will not get the callback anymore.
   
   We have synchronized (pendingMarkDeleteOps) for both create cursor failure and `internalAsyncMarkDelete`, if triggered the ledger creation means the left thread got the lock and the right thread can only get the lock after the `mdEntry` is added to the `pendingMarkDeleteOps `, no?
