I was looking around the cfs code and thought that it
may be interesting to hook the #M mnt device to the
vm system and have it cache data in unused memory.

Memory used by the cache would considered free by the
vm system so processes have first dibs.

This seems the best place to put this kind of caching
since it is where calls get converted to messages and
multiplexing here will allow the cache to be shared
by all processes.

Comments?
