> Method waitForTempReplica() polls every 100ms during block replication, 
> attempting to "catch" a datanode in the state of having a TEMPORARY replica.  
> But examination of a current Hudson test failure log shows that the replica 
> goes from "start" to "TEMPORARY" to "FINALIZED" in only 50ms, so of course 
> the poll usually misses it.
