ELKS draws on v7 and on Minix for its origins. It takes an old v7 unix
type view of kernel dynamic memory allocators (that is -don't do it-),
user space memory is handled by a simple linked list of holes. We have
two entries per process maximum (data and code) so kernel side its just
not worth the clever stuff.

Much of the other ELKS stuff is like this. We have no hash for the
buffer cache because we tend to have about ten buffers cached...
