This change allows us to reduce the chunk size to the point that allocations larger than half a page are always page-aligned. This isn't very useful for production, but it should help in debugging programs that assume large allocations are page-aligned. If a program runs okay with MALLOC_OPTIONS=kkkkkkkkkkkk, but not with the default chunk size, then it's a good indication that the application is making bad alignment assumptions for large-ish objects.
This might be useful for narrowing down some of the X problems that have been reported for xorg on amd64.
