That's where I was going with the silly idea to use another
allocator :)

Really, it would be great if we could treat kmalloc() objects
just like real pages.  Everything wants to do I/O on pages
but sometimes (like the networking) you have a kmalloc
chunk which is technically just a part of a page.

The fact that there is no easy way to make this work is
frustrating :-)
