   1) The gnu-emacs manual I have(6th edition, version 18, Marh 1987) talk
   about protection against simultaneous editing on page 88, sec. 15.3.2. 
   I don't the behavior that this part of the manual talks about in that
   when I edit the same buffer from two different emacs sessions I do not
   get a warning message.  I also noticed the file userlock.el in my emacs
   lisp directory which seems to be the support for this function but when
   I loaded this file in with the load-library command I still didn't get
   the desired behavior.

I had to make the lock directory myself -- the build process didn't do
it for me (I didn't use the "build-insatll" script, maybe that does) --
if it doesn't exist you don't get file locking.  Also, the lock isn't
created until the buffer is modified.  Modify it in the first window;
you should get a warning when you subsequently try to modify the
buffer in the other window.  Oh, also, you should find the file twice,
and not just put the file up in 2 windows -- it must be in 2 different
buffers.
