There's a figure on page 16 of Adrian Nye's ``Xlib Programming Manual'' which 
looks like this:



            ---+   Network
               |    | |    Events In  +-+-+-+-+-+-+-+-+
               v    | |    +--------->| | | | | | | | |  Client 1 Queue
             +---+  | |    |          +-+-+-+-+-+-+-+-+
Server Queue |   |  | |    |
             +---+  | |    |          +-+-+-+-+-+-+-+-+
             |   |  | |    |--------->| | | | | | | | |  Client 2 Queue
             +---+  | |    |          +-+-+-+-+-+-+-+-+
               |    | |    |
               +--->| |--->|
                    | |

I'd to know if the events really are being read off of the network at a
single point and redistributed to the clients.  I haven't found any evidence
of this in the Xlib source, but I still wonder what was meant by this figure.

For background, let me state that I'm interested in building a multi-level
secure X window system, and I *don't* want to have to trust the Xlib (client
-side) of things.
