I support your proposal.  But, have a question:  Has
anyone actually measured the performance impact of 
INVARIANTS?  I'm tempted to suggest that INVARIANTS
should be the default in not only -current in 5.0
when she's released.  Anyone interested in performance
in 5.0 will build custom kernels, and so he can turn
INVARIANTS off.
