I was flipping through the MIT - C Language X Interface the other day 
and while reading the part about server resets (2.6), I noticed that 
a server reset occurs when the last client closes it's connection 
and is in close_mode of DestroyAll (default).  But it does NOT happen
with close_mode of RetainTemporary or RetainPermanent.

A common problem that I encounter with novice users of X is their
"ignorance" of server resets.  A common scenario:
    X &			start server
    xhost +foobie	add machine "foobie" to access list
    xhost		show access list - foobie is not there!

Ahh, that good ole server reset strikes again.

So I changed xhost to do an:

	XSetCloseDownMode(dpy, RetainPermanent);

right after the XOpenDisplay and it solved my "problem".

Now just for academic debate, is there anything wrong with
changing the close down mode for xhost?  I can't think of
any resources that are wasted by this.

I know all about XDM and several of the other methods for
starting the server so please ignore them for this discussion.
As a matter of fact I encourage our users to use XDM.

My obligatory:  "I'm running on an Intergraph 6040 under X11 R4 
with patchlevel 14 and I am standing on one foot, patting my head...."
