/* On Windows, a pipe is a struct containing a UUID and a handle.  Both the 
   UUID and handle are supplied by the client.  
   
   The UUID is used to build the client's reply endpoint.  
   
   The handle is to the requesting client thread's thread local storage struct,
   so that the client's one and only reply handler can put reply data where
   the requesting thread will be able to see it.
