Yes, I was running a kernel for a short while w/ INVARIANTS and WITNESS, but 
it was basically useless after a couple of hours under load under the giant 
lock.  How much of a performance hit is just WITNESS?

(I also got a "me too" message from someone privately who experianced the same 
issue after a 5.1->5.2 update)
