Luke, could you say a bit more about R-uthreads, what your ideas,
goals, and conclusions there were?

I see the old R-uthreads branch in svn (looks like it was based on R
1.4 back in Aug. 2001), but I couldn't find any summary discussion,
and I can't tell much just from looking at "src/main/uthreads.c".
