Title: Potential keyed join deadlock

A previous change in gh-416, could lead to deadlock in full keyed joins,
that were stopped (e.g. via choosen) quickly.
The fetch handlers request thread was cancelled on stop, but needed to
remain listening until other nodes had done, so that it could acknowledge
stop
