I only read the slides.

The extra background (and repetition) was helpful to me in filling in 
things, especially about Windows, that I could not follow in the 
discussion a year ago. But I noticed that it might be tedious to people 
already familiar with the subject.

A working and useful Windows-only PyParallel (integrated with CPython or 
not) might help stimulate open-source *nix improvements to match the new 
Windows stuff.

Just reading the slides, I did not pick up as much confrontation and 
blame as you did. I certainly appreciate that asyncio is working *now*, 
and on all three major target systems. I look forward to looking at the 
doc when it is added. I will understand a bit better for having read 
Trent's slides.
