Of mucho importance: Documentation!

Critical clean-up activities:
-----------------------------

1. Regression tests (for both performance and correctness)
2. Crash recovery of local storage
   -- XN
   -- C-FFS
3. Support for <ctl>-C
   -- signals and process groups
4. Real use of capabilities
   -- also, protection in XN
   -- also, clean up system calls (protection)
5. Clean XN/BC/pmap interactions
   -- do XN protection check during mapping of BC pages
   -- remove XN registry entries appropriately
   -- check with XN before considering a BC entry reclaimable
6. Allow page table sharing and use it for fork
7. Expose ppage structures and have explicit (rather than implicit) allocation.
8. Real dynamic shared libraries.
9. Elimination of the remaining global shared memory structures.
    -- file descriptors/filps
    -- UDP socket information
    -- mount table
    -- what else??
10. Find and fix the lingering random process crashes!!
11. Clean the ExOS level VM and physical page allocation mechanisms
    -- uniform support for allocating either with particular behavioral
       characteristics (e.g., shared across forks, shared across execs,
       immediately allocated physical pages, writeable or not, etc...)
12. Add support for registering "atPrologue" and "atEpilogue" functions
13. Fix time management to avoid both the current skew from the rest of
    the world, and the time reversal that was previously preventing skew.
14. Fix TCP sockets to correctly support inaddr for both bind and getsockname.
15. Fix strip or the reason we can't boot xok made xok (only xok.gdb)

Additional functionality needed:
--------------------------------
1. Page revocation and paging/swapping.
2. More drivers (e.g., IDE, other networks).
3. Harvest and NCSA (for HTTP server comparisons).
4. Fast NFS server.
5. X (client and server)
6. Better binary layout - perhaps ELF
7. Native debugger
8. Some type of per-process access to LDT (local descriptor table)
	to enable emulation of NetBSD, for example
