 Fixed BUG#19217 "dict_load_indexes() may read the delete-mark incorrectly".

too much memory. Instead, either create the equvalent SEL_TREE manually, or create only two ranges that
strictly include the area to scan
(Note: just to re-iterate: increasing NOT_IN_IGNORE_THRESHOLD will make optimization run slower for big 
IN-lists, but the server will not run out of memory. O(N^2) memory use has been eliminated)

small cleanup fixes in kernel/vm/Configuration
