allow regions to have reserved areas

+ A reserved area is an area at the start of the region that should not
  be used unless explicitly asked for, for example null pages.

  As such, a small correction to my previous commit message: There's no
  danger in not locking req_mem() etc, as a null page will only be
  allocated when explicitly asked for.
