Cut down the initial db checked hash allocation somewhat
- The instance numbers are often much much bigger than the number
of actual packages, and the hash table grows automatically as needed
so there's no need to over-allocate at the start. Apply some
(fairly arbitrary) heuristics to limit the initial allocation size.
(cherry picked from commit e40a7c61c422e79838226c69cb84f7a624fa6127)
