If my reading of the spec is correct this only really applies in cases
where L > 1*SMSS.  As it stands right now, I'm using L=3D1*SMSS, so
behavior durring slow start will either be identical to, or more
conservative than the traditional algorithm.  With that said, it may be
beneficial to provide the option for using L=3D2*SMSS and have a sysctl
for that.
