Maybe we end up allocating a mapping that is too close to something
else, see:

https://stackoverflow.com/questions/56888725/why-is-map-growsdown-mapping-does-not-grow

I guess that we should make the initial mmap in find_free_range() larger
and return and adress that is quaranteed not to have a mapping that is
closer than 256 pages in the direction we want to grow.
