Deep within the recesses of my foggy memory, I remember something
about the u. structures in kernel memory being changed to a different
format, supposedly to facilitate either multi-threaded processes, or a
multi-threaded kernel.  I believe this may have been just after the
intro of 0.9, but I'm not positive.

What was the focus of those changes, and what was the end result?  Is
NetBSD a "multi-threaded kernel" (in whatever context), and will there
ever be a process thread library and/or any thread data
synchronization support?

My mind was just wandering down this avenue this morning, and I was
wondering just how robust and featureful any threading support might
be in NetBSD.  I remember a short-lived libpthread at one point in
time, but it hasn't been around for awhile.

Thanks for any enlightenment...
