As I said, the code doesn't use memalign.
Also by `memalign' I actually mean `posix_memalign' which has no known
broken implementation (but is recent and only part of a non-core element of
POSIX, so it's missing from several systems).
We already use `posix_memalign' actually, when available, to get the
multiple-of-1024 alignment used for cons_blocks (I introduced this when
I got rid of the markbit).
