I am interested in finding any information related to changes in the
Sample Server porting interfaces for R4.  I've heard about the 
substantial gains in performance of the R4 server and am curious as 
to whether this has been accomplished by equally substantial changes
in the ddx interfaces (specifically, those described in "Definition
of the Porting Layer for the X v11 Sample Server" ala Angebranndt,
Drewry, Karlton, and Newman).  I'm really more interested in interface
changes than changes to the ddx implementations (although I'm willing
to listen to anything :-).  I'm in the process of performance tuning 
an R3 server based upon them and don't want to go too far down any paths
which won't survive through R4 :-(.  Any help from server hacks with
access to R4-beta would be appreciated...

Please send responses directly to me and I'll summarize to the net
if there's interest.
