Comment (by varosi):

 hm, it's not a hackery, but platform specific. Is it needed all pages to
 be linked in a linked list? I mean that it is possible to realloc()
 current page until it is possible to resize it. That way we'll have less
 jumps and guard pages. So we'll have linked list, but from larger memory
 chunks.
