Review Comment:
* If rowsSinceCheck >= ROWS_PER_CHECK, the `estimateMemory` will be called
the same as before
* If rowsSinceCheck < ROWS_PER_CHECK, the `estimateMemory` will be called
`ROWS_PER_CHECK / VectorizedRowBatch.size` times, and `5000 / 1024 = 4` times
by default, I think this is much smaller overhead in the overall computation.
