Okay, summing up: the first five points seem rather uncontentious, with reservations on Endre’s part concerning the extensibility of message queues (I’d love to hakk on that with you sometime—when...

I have updated the PR to include a very simple Restarter (which is powerful enough to support all previously existing test cases), see [the test](https://github.com/akka/akka/pull/21128/files#diff-dfcd8ae24995799ab6ae009809918b65R99) and [the implementation](https://github.com/akka/akka/pull/21128/files#diff-a5bbad107a127e344dae36893abfd09cR1). Concerning the...

To me an extension is an active piece that extends the functionality of the ActorSystem. If serialization is regarded as a service that needs management in terms of resource consumption...

Is the scope for this “important caching” really the ActorSystem? Why is it not the remote transport or the JVM or the classloader?

Okay: the purpose of asking these questions is to arrive at the essence of what it is that we need. With the actor-based approach we already have singletons (per system)...

Yes, that might be a reasonable approach as well: since we know that certain things (like Serialization) are needed, they are not really extensions but rather essential parts. At least...

But before we go there we should be sure about the API, I remember there being an open point concerning streaming serializers.

The difficulty is that the first step will be a rather large one because the machinery to let an actor run is not that simple. But we can of course...

To pass the tests it must support child actor creation, but perhaps you are right. I have three hours on a train now, let's see …

I’m currently sketching it out in my head (and taking some notes): if all those things mentioned in #18 are actually removed, then the initial step might actually be of...
