Hi Ken,

I'm unfamiliar so far with the content of the concurrency branch, what changes
it makes, and the threading model it proposes.  Could you please summarize the
state of the art for me, so that I know what this branch entails?

Opening a general discussion about concurrency is something I'd like to do
soon, but not until I better understand what has already taken place.

Thank you,
  John
