-- mlength will memoize itself over each element of 'keys', returning
-- the memoized result the second time around.  Then we move onto
-- keys2, and while we're doing this the first lot of memo table
-- entries can be purged.  Finally, we do a large computation
-- (length [1..10000]) to allow time for the memo table to be fully
-- purged.
