The queries _are_ responsive now.

AppID: steprep-demo
When: query non-responsive approx. between 12p and 2p PDT yesterday
(2010-07-08) - the mapper job ran approx from 11a to 12p
Query: SELECT __key__ FROM AccountKeyword WHERE nextUpdateTime < :1
ORDER BY nextUpdateTime ASC  (where :1 is now)

(Looks like it's not actually a composite index involved.)

Let me know if you need more info,
