Zen: Committing last catalog file on zen dev server that was not committed last week; Should be reviewed by someone though (maybe emma?) as there are a lot of changes and I'm not sure who did them.
Speed up query 10x by using exists on the acs_object_party_privilege_mapinstead of an explicit join. The join causes a sequential scan ofacs_object_context_index.
when threads are started during bootup, these threads do not contain any library functions (not even ::db_*). This change provides support to correct this for threads created vi ::xotcl::THREAD.
Removed the previous changes, they need to go in blank master so the .lrntoolbar will work with sloan and selva (sigh). Really need to work up away for packages themselves to pass up toolbars.
