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.
