Yeah, I looked at the code and am rewriting.  I think I can get it down pretty 
small and unobtrusive, but, question:

If mremap() fails, do I still have to unmap the old address for 
FEATURE_CLEAN_UP, or does the remap do that for me?

The man page doesn't say.  I _think_ I have to do it myself.  And of course 
I'm wondering for the nommu systems, can we use remap at all?
