Subject: [PATCH] Rolling back part of the last commit;  the correction to the
 tile allocation fixes the issue with memory being grabbed constantly and
 never released, but re-surfaces an error with tiles being used after being
 freed.  This is assumed to be a long-standing bug that has not been found
 yet.  Meanwhile, the error that uses up excess memory is better than the
 error that causes layouts to get completely screwed up.
