Please. Even if it need an eventual deeper rework to be totally generic, 
I think we need to start moving things in that generic direction. 
Baruch's case is a clear example where non-arm code could share it, so I 
think that's at least a good proof point that sharing is actually needed 
(rather then just for theoretical reasons).
