> SuperColumn deserialization hits a worst case insert scenario for CSLM:
> inserting pre-sorted entries one at a time. Inside of CSLM this requires
> scanning to the end of the list and doing a comparison at every step for
> every item inserted. This patch supplies a SortedMap interface to the
> supercolumn deserialization. CSLM will do a bulk insert from a SortedMap
> interface supplied in the constructor.
