Elsewhere you've said that there are performance downsides to
context.become, specifically that this is the reason sender() is a function
rather than doing something like def receive(sender: ActorRef): Receive = {
... }, which would eliminate the problem of closing over sender() in
futures within a receive.
Does the concern only come into play when calling context.become
potentially thousands of times per second? I can see how that would
probably lead to GC issues.
