From: John Harrison <john.c.harri...@intel.com>
Cache the key count value rather than querying the hash every time.
Also assert that the database does not magically change size after the
fixups.
v2: Rename variable according to style guide [Tvrtko]
v3: Reverted accidental style change and added a blank line. [Tvrtko]
