trait FutureSupervisor extends AnyRef

Alert if a future does not complete within the prescribed duration

We use future based synchronisation in some places, where we use a promise to only kick off an action once a promise is completed. This can lead to deadlocks where something does not start because we never complete the promise. This leads to hard to debug situations. We can support debugging by tracking such futures. As this is costly, we'll turn this off in production.
