Maybe, but then the bugs that show up only without MKDEBUG won't happen.
Really there need to be builds of the power set of options, but of
course that's infeasible.  It seems the autobuilds catch 98% of the bugs
that break any remotely common builds already, so there's not much gain
in spiffing that up.  If anything, I'd like to see builds with
DIAGNOSTIC and LOCKDEBUG run through atf.
