[Bro] Time Machine RAM usage question

That's what I originally thought.  What was throwing me was when I
would try to find packets any older than the cutoff, the queries would
come up empty, the log showing something like "query not found in
connection table."  So I ran "show conn sample" to see the connections
table, and the oldest connections were always at the cutoff.  When I
looked through the source code, it appeared that connections older
than the cutoff were evicted from the connections table, but the query
depended on the connections table to find the packets on disk/ram.
