if one node is just slow enough in responding that it
falls outside the timeout, you could get an annoying situation
where that node is out-of-step forever after. i guess it depends
how often incoming lines arrive. if it's an interactive
session, i guess it might not matter too much - i can see
how this might be useful controlling many shell
sessions at once. you could make things more reliable by
tagging requests and replies, but even then there's the
question of what to do when sessions diverge (assuming
that's what you're doing). interesting.
