Memory fragmentation would probably be a BIG issue. You have short
[kv]malloc-ed reigions, which normally last for the remainder of the uptime.
We really need some sort of active memory defragmentation... Then again,
almost all of the reigions would be allocated near boottime (before init is
loaded), so they should be around other reigions with similar lifetimes.
But I think that supporting files with contents would definitly be a win
(the VFS can handle pretty much everything except the acatual storing and
reading of file contents).
