There is two part in this module :

* memory-page :
    It is a page allocator using bins. Each bin is a list (or a splay tree)
    of the same power-of-2 pages. If no page left in a bin, it tries to
    allocate a large page to split into two pages. Page size are :
    512 B, 1 KB, 2 KB, 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB,
    256 KB, 512 KB, 1 MB and 2 MB. Alignment of a page is the same
    value than for its size.

* memory-slab :
    using slab for smaller blocks, but much simpler than Linux' slab.
