I was reading an older news article comparing FreeBSD's SMPng and

scale as good as Linux?
not even close.  we're still under the giant lock.

Could you take a guess (just for being informed) how much of the system 
is under the BGL and how much is MPSAFE?
Even more interesting would be a guess of how good it might scale when 
you finally get rid of BGL.
