Yeah, that's a good idea.
Hajime, another question, do you really want a malloc/free backend? I'm not a mm expert, but does malloc() behave exactly as the kernel counter parts?
In UML we allocate a big file on the host side, mmap() it and give this mapping to the kernel as physical memory such that any kernel allocator can work with it.
