Lou DeGenaro resolved UIMA-4341.
--------------------------------
    Resolution: Fixed

Code delivered.

JD now keeps a map of work items comprising status changes which is written to disk during OR publication receipt processing. 

A work item is added/updated in the map when its status changes and is removed upon writing its status to disk.

Previously, each work item status change was immediately written to disk.  For Jobs with large numbers of work items this soon became a performance bottleneck.
