The part of the external sort code that does external sorting should be re-entrant, and shouldn't need to consult global variables (such as dbpath). This would make it more testable, and easier to use to index multiple collections at once. It should also separate the external sort functionality from bson index building / comparison functionality, again for separate testability.
