      In at least certain cases, inserts do not re-check the shard they were sent to when receiving a bad version in checkShardVersion. This can lead to misdirected inserts if migrations are heavy, particularly if migrations are taking a lot of resources. (this, along with SERVER-4603, may be impacting mrShardedOutput.js/bigMapReduce.js).

      Solution - probably refactor this code in line with the new pcursor stuff.
