Yep...  That is where alot of the complexity is coming in.

Not really, lets see how things work first :-).  Also, if I was really
a stud, I wouldn't be working on FreeBSD all night, but would have other
interests :-).  Now, I am working on FreeBSD for both my full time
job and after hours...

The stuff is going to be preliminary, and there is a lot of coordination
that is needed between me and the "real" SMP crew.  What I am doing is
mostly going to be a "proposal" to both the SMP people, and my co-workers
at work for review and criticism.  As I know that you know, this has to
be done correctly -- I really don't want to create another "interesting"
thing like our VFS layering. :-).
