We have noticed, that, for some reason, if you do an xsetroot -solid <color>
instead of just using gray as your root window background, that it takes 
FOREVER to logout.  The server takes much longer to re-initialize itself, 
and in the meantime, any movement of the mouse will produce the message
"Errorlog buffer full: <n> errors missed".

If, instead you do an "xsetroot -grey or -gray" or just leave it at the 
default (in otherwords, don't select any color except gray) then logging 
out and getting the new login window just takes about 3-5 SECONDS,  not minutes.

It must have something to do with the colormap, but I cannot imagine why.

We still haven't figured out why we get crazy mouse motion when we try
to run the X11r3 server so we have to use DECwindows UWS 2.0 server. 
X11r3 works fine on our monochrome Vaxstation II, though.
