While there, maybe also do something with these semi-debug-ish
vm.pmap.pc_chunk_(allocs|frees) like change them to [u_]long too, move
under debug or just drop them? While they can be useful for someone,
pc_chunk_(allocs|frees) have also an "int" and quite quickly overflow.
Though e.g. vm.pmap.pv_entry_(allocs|frees) have a long.
