Don't assume there's always 8-bits for client id - use the mask or you'll
break on Xsun (uses 11 bits for client ids in some releases/configurations
to allow 1024 clients), servers based on older pre-Xorg X11 releases (only 
allocated 7 bits to client ids), and those who've compiled XFree86 or Xorg 
with different values of MAX_CLIENTS since Keith made it configurable a
few years back.
