  Minimum number of properties needed for a hash part to be included in the
  object property table.  This limit is checked whenever an object is resized.

  A hash part improves property lookup performance even for small objects,
  starting from roughly 4 properties.  However, this ignores the cost of
  setting up and managing the hash part, which is offset only if property
  lookups made through the hash part can offset the setup cost.  A hash part
  is worth it for heavily accessed small objects or large objects (even those
  accessed quite infrequently).  The limit doesn't take into account property
  access frequency, so it is necessarily a compromise.

  A lower value improves performance (a value as low a 4-8 can be useful)
  while a higher value conserves memory.
