be947d4e7fb2 Initial revision claus parents: diff changeset	42	This class provides common protocol for all external streams which are
be947d4e7fb2 Initial revision claus parents: diff changeset	43	unbound in size (i.e. have no end). Examples of these are PipeStream,
be947d4e7fb2 Initial revision claus parents: diff changeset	44	Sockets, TTYStreams etc.
