Ticket 2404 - fixture delete order
 r2719@asus:  jeremy | 2005-10-23 15:01:13 -0700
 Keep closer tabs on dirty, loaded, and declared fixtures.  Closes #2404.
 r2720@asus:  jeremy | 2005-10-23 16:09:19 -0700
 ensure table names are strings.  set dirty = dirty union loaded rather than dirty = loaded.
