  Just an update:
SO_SNDLOWAT sets the low water mark, but
SO_SNDBUF set the high-water mark.
  The names don't match for purely historical reasons.

 The only other intersting socket options are
 TCP_MAXSEG, which can only **reduce** the
packet size, useful for cases where all of: 
1) the default is too big, 2) fragmentation is happening
and 3) the link is lossy are true...

  max xmit = 65,535, so it won't limit this...

  This means the numbers reported here many moons
ago (graph attached) are intersting: they're
from a previous experiment on an older linux
machine.
  The twitch in writes is odd: perhaps your work
will help me figure it out. Feel free to email.
