do not grow dbsize agressively
Only grow the database size when the high watermark increases.
We also grows the database size a little bit aggressively to
save a few ftruncates.
I have tested this on various environments. The performance impact
is ignorable with 16MB over allocation. Without over allocation,
the performance might decrease 100% when each Tx.Commit needs a new
page on a very slow disk (seek time dominates the total write).
