Actor style concurrency exists for many other language platforms. See Akka for JVM/Scala or Seastar for C++.

I'm somewhat skeptical of GC pauses being a problem in anything that's not actual hard real time like avionics or manufacturing equipment or similar. What difference will a few hundred millisecond pause even make in an distributed async data pipeline? And that's on the higher end of pauses these days.

There's an excellent paper on GC pauses and its impact on Spark and Hadoop. "Trash Day" => https://www.usenix.org/node/189882

Sure, I understand pauses happen and there is a performance degradation, I'm asking whether it really matters in a processing framework that isn't controlling medical equipment or airline hydraulics. Is something going to break if there's a small pause? Especially in return for the productivity and safety of using managed runtimes?
