Thanks for the explanation.

My current problem is with this ..

   type Stream_Type
     (Buffer : access Ada.Streams.Stream_Element_Array)
   is new Ada.Streams.Root_Stream_Type with private;
   --  Provides an in-memory Stream over the elements of Buffer.
   --
   --  When one of these Stream_Types is created, it is notionally
   --  empty. If Buffer is not in fact empty (perhaps it has been read
   --  from a datagram socket), use Set_Last to indicate the index of
   --  the last valid element.

where having to initialize a buffer of size 2048 (say) with useless
data and then overwrite it by reading from a socket goes against the
grain. Perhaps I'll be able to find the Ada way of doing it and it
will be suitably elegant.
