-- Do an INSERT with a VALUES clause that contains 100,000 entries.  Verify
-- that this insert happens quickly (in less than 10 seconds).  Actually, the
-- insert will normally happen in less than 0.5 seconds on a workstation, but
-- we allow plenty of overhead for slower machines.  The speed test checks
-- for an O(N*N) inefficiency that was once in the code and that would make
-- the insert run for over a minute.
