I think it's on the list; someone just needs to pick it up.  As I
understand it, it's a matter of taking various subsystems one at a time
and removing their need for the Giant Lock.  For example, I recall that
Jeffrey Hsu had come close to getting networking out from under the lock.

I don't think it would be possible to use FreeBSD's SMP mechanism; one of
the reasons DragonFly was forked was to avoid the shape FreeBSD's SMP
implementation was taking, at the time.
