This issue (and many other resource measurement issues) are solved in OpenVZ but not yet in lxc. In supplying the user a whole virtual image, they are able to shortcut many of the things that don't make sense if you are only sand boxing a single process. If you are managing a single process then you shouldn't expect to be able to sideline anything in successfully. If you do want to do that, then the single process model isn't the one you ought to use. I think it's reasonable for lxc to say that an exiting model doesn't fit but it feels very wasteful to throw away a whole raft of user land stuff.
