If I'm not mistaken: You can not tell mmap and mremap to explicitely
exchange two pages. (Mremap resizes an existing memory mapping.)

Perhaps I did not explain my idea good enough: I want something along
the lines "Current memory contents in page starting at address X move to
address Y and the contents of the page starting at address Y shall be
found at address X in future".
