Got to the office at 10:00am, still here at 10:30pm. Tired. Need to go home and sleep.
Think I got to the bottom of why the regression test is failing, finally. Also did a ton of cleanup work on the dstate serialization code. Should be much more maintainable and less likely to have crashes on unexpected input.
The bigger problem is I have not yet finished Christmas shopping and it's not clear when I'm going to be able to do it. Very annoying.
