  52         This function inspects the capacity, size, and maximum size of the dynamic
  53         buffer. Then it computes a natural read size given the passed-in upper limit.
  54         It favors a read size that does not require a reallocation, subject to a
  55         reasonable minimum to avoid tiny reads.
