# This file controls the 'external' job control engine, that (periodically #
# looks / somehow is pushed an event?) picks up new jobs, and processes them.
# 
# It then stores the progress/status, etc. in job and joblog tables as needed
# via wrapper functions.
#
# The whole pa_job_engine is multi-threaded, and uses the database tables for
# state management and communication back to the pa web site
