I wasn't thinking of going quite that far -- just enough smarts to know
when the necessary data will be either unavailable or garbage.

At this point I'm just going to rebuild the world with LOCKDEBUG as I'd
rather pay the price for having the debug information available on my
production SMP systems than not be able to reproduce such bugs on a test
system.

(I don't think I've ever seen any trouble with DEBUG vs. libkvm users on
sparc or i386 where I typically run DEBUG kernels on test systems and
non-DEBUG on production systems.)
