Right.  We can do some of this due to the recent MM rework by Paulus.
I know the complete flush will work, and once we get the kernel
running again we can fine tune the synonym search.  We have to be
careful about some of these complex functions to do these operations,
they could very well run mode code and do more hard to the cache
that just flushing it and getting on with life :-).

Hang on, we'll get it.
