The way you have worded that last sentence suggests it's not as stable
when doing builds.

Can you do a full build using both CPUs with a -current kernel without
experiencing any lockups or panics?  How about if there's a good bit of
NFS traffic also occuring (e.g. with sources on NFS)?

I certainly can't get very far with netbsd-1-6 on my 4000.  :-(

(though when it will run, such as when building a kernel for the second
time after everything's in the cache, the build runs almost exactly
twice as fast on two CPUs!  ;-)
