It seems desirable to me that we do not require acknowledging every message:
when the channel has data available, it sends that data along and doesn't
cache it.

I slightly prefer the divergent-path approach rather than the discard
approach, for one main reason: it means that we don't have to implement
special handling for actors which have already been "destructed" but are
still receiving messages.

I don't think my opinion is strong enough to *insist* on the divergent-path
approach, though. If we do go with the discard-bad-messages approach, I'd
like a very solid approach torwards zombie actor IDs.

In any case, I'm also concerned with getting a theoretically sound approach
implemented for plugin destructor races for 1.9.3.
