Using the vm_map() directly may be one approach. We already use
pthread_mach_thread_np in part of the porting effort. As it will
be allocating a tremendous amount of memory and efficient use is a
goal, over-allocating and doing alignment ourselves isn't the right
approach.
All allocations larger than 4k are page-aligned by default. If you
want blocks guaranteed to start on 64k virtual address boundaries,
create a custom zone and factor all of your allocations thru one
function, padding sizes to mod 64k, and throw away the first 1-15
pages (up to 60k) for the initial alignment.
