Yup :) That's the best (from my POV) point of ufd -- the ability to delegate the descriptor to some other task. Though there are several limitations (I've expressed them in other e-mails), I'm definitely supporting this! The respective CRIU code is quite sloppy yet, I will try to brush one up and show soon.
