not for this release, but would the axfs be an option in the future with 
it's execute in place capability for key files? or is the performance 
difference compared to ram such that you wouldn't want it in any case?

either way, the profiling it does of which pages are used (and how much) 
could be useful in figuring out what binaries should be stored 
uncompressed.
