      This ticket has turned into a more general refactoring of the parallel cursor code, minimizing the use of getChunkManager(), but also includes the original issue:

      getChunkManager()'s failure mode is to throw masserts, which is incorrect as changes in sharding are not generally exception cases - this leads to very ugly logs and confusing codepaths. Also, there are various configurable levels of reloading for getChunkManager(), these should be clearer and encapsulated.
