Firstly thanks for such a detailed report Nat. It must have taken you 
an age to collate and write.

I am very surprised there was only seven of us who voted. It seemed 
like there was a lot more.

One point of mine not mentioned in the report is that I would really 
like to see Boost Fibers graphed against Windows Fibers on that 
performance scaling graph. We know Windows Fibers are probably close 
to optimal performance given all the tuning done to them thanks to 
SQL Server competitions, therefore if we see the same scaling trend 
with Fiber as Windows Fibers (even if a tenth of the absolute 
performance) then we know the design is probably right and doesn't 
contain any "gotchas".
