Dave I understand your point for generic code and I was not all asking 
to rename anything in generic code.

My point was new code getting added to RDS to support this zero copy
message option. Within RDS, core code is common and all the 
infrastructure with it and it will be hard to follow the code if
that distinction is not maintained.

Ofcourse you have a last say on this list so if you want to
over rule the comment, I will step back :-)
