Oh, I found the flaw in my testing: there are two INSERTs in the test
script and I was changing only one of them.  After correcting that,
the results behave a little more sanely:
              Line Coverage           Functions
1 row:         70.4 %    349 / 496    93.1 %    27 / 29
10 row:        73.6 %    365 / 496    93.1 %    27 / 29
100 rows:      73.6 %    365 / 496    93.1 %    27 / 29
1000 rows:     75.4 %    374 / 496    93.1 %    27 / 29

Still, we've reached the most coverage this test can give us at 1000
rows, which still means it's wasting the last 99% of its runtime.
