I have entries in my slow query log for identical queries but, as you can see from the log entries below (including one irrelevant query), the number rows examined and returned varies. The tables are _not_ being updated.
The query cache is 'on demand', so I'm also not sure why the subsequent queries were not dealt with by the query cache. Any ideas?
