concurrent sysctl implementation

[jt at 0xabadba.be]

Hackers,

     I've been using FreeBSD since a boy and now its time for me to give
back.  I will be doing my final projects in university concerning
concurrency in the FreeBSD Kernel.  I've been discussing with Ed@ methods of
implementing sysctl concurrently since we use sysctl quite a lot for
_everything_ essentially (make, general kernel information, etc).  I've been
reading the sysctl man pages and some of the code in the kernel; however, I
wanted to shoot this out to the public since many of you know better than I
do about where I should be looking to do the required reading to get the job
done correctly.  I'm also open to implementing other things once this is
done.  I hope everyone is doing well.

respectfully,
