All blocks in the GC that are more than 16 bytes are aligned by
32 bytes. You shouldn't have any 16 byte blocks here, because
each element is 32 bytes long.
However, if your block grows to a page size, the alignment will
be 16 bytes off (due to the metadata stored at the front of the
block).
A page size is 4096 bytes. So anything larger than 2048 will
require a page-sized block or larger.
I would guess that once your array gets longer than.... 63
elements, it's always misaligned?
Quality sleuthing Steve. The program says it found misalignments
with 37 out of 100 attempts of length [1..100].
