How does Akka stack up in regards to providing these attributes on the JVM?

[pathsjs]

Akka actors are multiplexed on real JVM threads. So they implement a cooperative model of threading (i.e. you'd better not block for long inside the body of an actor)

Unless Akka provides a compiler, it doesn't allow much of the style Erlang was developed for.
