	Well - we pay attention to it as we write the code :-) [ a little at
least ]. Ultimately zero copy has most scope inside the kernel and at
the kernel <-> userspace edge.

	We used to try to avoid copying 'in' strings out of the incoming socket
buffers - which worked nicely, although it somewhat complicates the
'free' logic; we could do the same for some sequences I imagine;
ultimately though often the complexity - and the memory management
semantics make this not such an attractive thing to do though. IMHO.

	Regards,

		Michael.
