I was running a script to update the revert tables on db1047 with stat1 two days ago that had some bad disk access patterns.  (FYI, don't use python shelve as an on-disk cache of a dict().)  As soon as I saw the load come up, I killed the script.  For any difficulty that occurred in the meantime, I'm very sorry.  I've since re-written things to behave much better.  

I currently have two processes running on the machine: 

• sessions.py - Updating session table on db1047.  Useful for measuring editor labor hours.
• reverts.py - Updating revert tables on db1047.  Fixed to not need a disk cache.
