	would you care to elaborate on this? Version 3.51 (as opposed to
RELEASE 3) is supposed to pass SVVD for Sys5r2, and some of the optional
network hacks in the kernal look to me to at least resemble Sys5r3 code,
along with shared libs & loadable device-drivers, neither of which are
Sys5r[012]. I know that there are some differences and some 3b1 specific
goodies/features/bugs, but I don't know what they are exactly except that
the optimizer doesn't work (well, sort of), and some commands are missing.

	Has anyone played with the Shared-libs much? Like getting around the
duplicate symbol problems w/ curses? I would like to add code to the shlib.
Has anyone done this? whats the format (or is their one? is it raw object
code catted together?) I know about the symbol addresses in shlib.ifile,
they stop ~128K past the 4meg mark, which leaves 375K of the 512K allocated.
I would be interested in using this memory if I could have it.

(Brant - have you considered putting most of emacs up there?)
