> And then cause load procedures failure.
> This is because we do not execute RegionRemoteProcedureBase.persistAndWake 
> method in PEWorker, so even if we hold the procedureExecutionLock in 
> rollback, they could be executed concurrently.
> So it is possible that in rollback, we set the state to ROLLEDBACK and delete 
> the procedure, and then in persistAndWake, we persist the ROLLEDBACK state to 
> procedure store.
