to gracefully shut down a state in Executor you have to call one
of the terminate functions and afterwards call updateStates() to notify
the searchers. The resp. state is added to removedStates automatically
in terminateState() and removedStates is only used to forward the
information to the searchers. Currently there is no clean way to
terminate a state in a searcher (we discussed that internally a while
ago). What you could do is:

- initialise your searcher with a reference to the executor or
- mark the state (or return tuple in select() etc.) and adapt the main
  interpreter loop (select/delete until un-marked state found)

The 2nd option is less error-prone.


Kind regards,

Frank
