To do this, you need to iterate, attaching more until they are
all done.  In most cases, this is not the right thing anyway:
you want a `concentrator' node (typically not actual hardware,
and not in the config tree) that sits between the hardware
and the user interface, so that, e.g., you have:

	 tty I/F    HDLC (net) I/F    mouse I/F
	       \           |           /
	         \         |         /
	           \       |       /
	             \     |     /

Information passes across whichever `wire' is actually talking to
the hardware, and the other two are dead connections (or nonexistent).
This is how Streams *should* work (and is not how it does in SysV,
where they added a horrendous thing for multiplexing streams).
