Suppression of ro BR token when reading at RO mode

A BR token is used to keep cache coherency of data across nodes. We experienced that 'ro BR' token is requested by each node even other nodes read the same rage of data at the same time. Unless the range is never changed by all nodes, getting of ro BR token is not always required.
With the current design specifications, if the node getting ro BR token hangs up for some reason, other nodes have to be waited until the hang-up node is expelled, even though other nodes just want to read the range.
Thus I would request all other nodes could read data without waiting for hang-up nodes expelled.
