+==== 04/25 ====
+PK - Decided to take a chance to write super-TCP. Came up with plan. Spent 24 hours straight on it. Concluded it is too big for this late in the semester.
+==== 04/27 ====
+PK - AB - several hour meeting came up with concrete plan for finishing this project.
+PK - started over again.
+==== 04/28 ====
+PK - experimented with blocking and non-blocking socket member. With non-blocking I crashed my computer every time when I hammered the adapter but did not do this with blocking set. Flag must do something :). Later this day: First fully functioning version of new client / server.
+PK - AB - meet for an hour for code review, status.
+PK - a few more hours in. I added three more transmission "models" to the client: load,burst and random. I have replaced the processor based clock and am now using DateTime.Now.Ticks to make the code portable to Linux. This means same-machine/same-subnet RTTs are 0. I added the adapter cumulative loss/ooo counts. I added timestamps in acks. Have conclusive evidence that the blocking socket flag does nothing in UDP. Forced to put in Thread.SpinWait every N bulk transmissions so that we don't spill so many segments on the floor, even before they've hit the wire.
