Hi, I noticed a trivial typo in array.c, and it fails building struct.c

If you have a chance, can you try some concurrent benchmarks with fork
based on CPU core count?  Numbers based on both physical and virtual
(hyperthreaded) cores would be nice.

Contention between multiple processes might make the effect of cache
alignment more realistic and apparent (but with non-shared memory,
perhaps not...)
