Personally I've had this combo segfault a couple of times in the past year or so, which never happened with screen or tmux. I've been using dvtm+dtach for a while now and had no problems.

abduco also used to leave cruft around if it didn't shut down cleanly (e.g. laptop battery cutting out), which would confuse it when next starting up (trying to attach to a non-existent session). I saw some entries in the changelog which might have fixed this, but I've had no problems from dtach so not felt a reason to switch back.
