Remove ill-conceived concept of watches blocking reply on connection which did write/mkdir/rm/setperm etc.
This causes deadlocks in real life, and I can't see a sane way of avoiding them: it is reasonable for someone to ignore watch notifications while doing other actions, and that means that we can do other writes. These writes can block pending other watchers; if one of these is the process blocked awaiting our ack, we deadlock.
