When watching many (5000) actors at the same time the
following problems were found:
* first send of a sys msg is sent without any flow control
=> limit the number of outstanding sys msg by using
the buffer to send them later (ordinary resend)
* when msg cannot be written sys msg is dropped (relying on resend),
but that cause message re-ordering and negative acknowledgment,
which is very costly
=> buffer the sys msg on write failure
=> minor optimization of AckedReceiveBuffer
I also made the resend-limit configurable.

Akka
We believe that writing correct concurrent & distributed, resilient and elastic applications is too hard. Most of the time it's because we are using the wrong tools and the wrong level of abstraction.
Akka is here to change that.
Using the Actor Model we raise the abstraction level and provide a better platform to build correct concurrent and scalable applications.
For resilience we adopt the "Let it crash" model which the telecom industry has used with great success to build applications that self-heal and systems that never stop.
Actors also provide the abstraction for transparent distribution and the basis for truly scalable and fault-tolerant applications.
