Thanks.  24.2s -> 16.5s on my environment.

I actually tried with ruby-benchmark-suite and Michael's patch.
But I couldn't confirm improvement by setting GC.malloc_limit.  Now
I'm sure that in this case, the performance improvement seems to be
achieved by changing HEAP_MIN_SLOTS, rather than MALLOC_LIMIT.

Note that the model is *just my opinion* :-)

I even know some committers dislike such a performance configuration.
I don't know matz's opinion, but I expect him to dislike too.
