Euh. So I don't think it would actually be that hard, but we do need
protobuf (p.haul imports crit, which imports protobufs), and as near
as I can tell, google isn't interested in porting python's protobuf
libraries to python3:

it might be possible with some hacks it looks like, but I'd hate to
rely on those. There is an out of tree LXC binding for python2, but it
is not well maintained. I wonder if fork + exec is the best option
here. :(
