I think blocking the release of a non-alpha on this feature is a bit nutty.
Not to undermine the work, but it only affects users who run security and
want to be able to move a NN/JT from one IP to another without killing
currently running jobs. Only a small fraction of the user base enables
security at all, and an even smaller fraction regularly wants to migrate a
master to a new IP mid-job.
