Refs #28993 The previous `nextDeadline - time < 0` required that nanoTime resolution is actually high enough to see that the deadline had already passed. If it had not, the current keep alive was missed and also all future ones (until another a regular element would trigger another push/pull cycle). Now, with `>=` it also works in that case and just fails noisily if our assumptions are not true. It's not clear how it could have happened. On my machine, timers trigger 1-2 tick-durations too late (but at least ~2ms). How that could be the same in terms of the nanoTime resolution is hard to see. |

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. This model is a perfect match for the principles laid out in the Reactive Manifesto.
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.
