- posix_memalign() does not set errno, it returns 0 or an error number (maybe a jemalloc() vs. phkmalloc() issue, but also how the opengroup documents it.) - since "align" must be >= sizeof(void *), expect to fail align=4 on LP64 systems. - while i'm here, add a test for align=2 failing everywhere.
