#12257: wpdb Scales Badly Due to Unnecessary Copies of All Query Results

Comment(by ryan):
I did some quick profiling of a typical front page request with 6 posts.
The patch reduced peak memory usage a small amount ( 14,912,496 before vs.
14,877,440 after). Short apache bench runs show the patch to be a bit
faster. I haven't noticed any bugs so far.
I'll try testing with some big result sets to see how peak memory usage
behaves.
