Definitely, that's a better path. After looking at VHE patches,
I would probably leave V3 the way it is (keeping deactivate_xxxx:
symmetric). Marc has Reviewed V3 and you commented either way was
fine with you, so V3 should be ok.

Jumping on VHE is little too much at this time, thanks for the
alternative I kind of got myself into a jam here.
