>
> These optimizations are possible:
> - now on exchange GridDhtPartitionsSingleMessage is processed inside exchange
> future exclusive lock
> - GridDhtPartitionTopology.update always creates copies of node2part,
> part2node maps
> - it is possible for joning node do not send GridDhtPartitionsSingleMessage
> since we know in advance it does not have any data
> - method GridDhtPartitionTopology.update returns map copy which is not
> actually used
