I'd like to hear some additional opinions from the list on this: 
the existing socket API for TCP etc.  already uses ZEROCOPY, and other

line wraps), I'm not seeing much value in this.

sure I can do that, either  when I put out patch v3 or later today,
after others have had a chance to review this.
