Patrik Nordwall dec53381b6 =rem #17554 Improve flow control of system message delivery ... 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.
