I'm just exposing counters. I see few inconsistencies, though. The number of pcacheQueryURL values corresponds to pcacheNumQueries, but the pcacheNumEntries seems quite erratic. Different executions of test020 report a number of cached entries ranging from 10 to 12. Searching the cache with the privDB control always returns 10 entries with pcacheQueryID=* in the cache. After cleanup, the counter in fact drops by 10, although the database is empty (apart from the glue entries, of course). p.
