during invoking of doUpdates()

> Currently, the namenode and each datanode reports 'blocksreplicatedpersec.'
> We'd like to be able to graph pending replications, vs number of under
> replicated blocks, vs. replications per second, so that we can get a better
> idea of the replication activity within the DFS.
