Preliminary data. Today's "TOP 10" List.
Please note that none of the DNS items would show up with internal testing,
since we don't have a wide number of domains in the test data.
Traces 34780, 5954, 5960 and 24996 require explanation, even though the
majority of allocations at those sites are obviously being reclaimed. The
DNS still could be part of the cache.
