 5   -- Allocation and recycling of ARRAY[INTEGER] of decreasing size.
 6   -- SE runs fast, since it does not try to mark the contents of these
 7   -- arrays.
 8   -- Compiled with SmartEiffel, this benchmark has an important memory
 9   -- footprint, because SE's GC does not merge or split memory blocks
10   -- and thus recycles poorly the dead arrays.??????
