> {{InvalidateBlocks#node2blocks}} uses an unordered {{LightWeightHashSet}} to store blocks
(to be invalidated) on the same DN. This causes poor ordering when a single DN has a large
number of blocks to invalidate. Blocks should be invalidated following the order of invalidation
commands -- at least roughly.
