For multithreading branch.  See

May I suggest to post some kind of design notes, with some details
about the above?  I think such preliminary discussions help get all
the interested parties up to speed, raise some important issues that
are best discovered sooner rather than later, and generally avoid
surprises, pleasant or otherwise.

I did something like that while I was working on bidi display, and my
experience with this was very positive, even though much less people
are interested in that subject than in GC.
