eh isn't this already possible with mmap and mremap ?

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".
