I was wondering why the file was misnamed ;)

I worry that

a) MM developers will forget to turn on the debug option (ask me about
   this) and the code in mm_init.c will break and 

b) The mm_init.c code is broken (or will break) on some architecture(s)
   and people who run that arch won't turn on the debug option either.

So hm.  I think that we should be more inclined to at least compile the
code even if we don't run it.  To catch compile-time breakage.

And it would be good if we could have a super-quick version of the checks
just so that more people at least partially run them.  Or something.
