I've heard through the grapevine, but am not sure yet, that UNIX V.4
shared libraries are fully paged, that is, you don't have to have
the whole library in RAM when a program was using it.  (As opposed
to the sorry situation in UNIX V.3)  If this is true, do V.4 ports
of X just stuff the server into a giant shared library?  This cuts
the overhead of the local transport down to a subroutine call.
(Well, maybe not.)  You need to have each run-time copy of the code
share control of the screen, using a semaphore (or two to avoid race
conditions) for a baton will do the trick.

To accept network connections, you still want to have an official
X server process; it will be handy to keep an official server process
around as a figurehead, and rig things somehow so that killing that
process shuts down the shared library ghosts.

Has anyone announced something like this?
