One fixed-size thread pool for its executors (event-loops, processors) which execute async tasks. Async tasks can be dispatched to this thread pool using tokio::spawn. And one dynamically sized but bounded (in size) thread pool for blocking tasks. By default, the latter will grow up to 512 threads.

In Java 1.1, green threads were the only threading model used by the Java virtual machine (JVM), at least on Solaris. As green threads have some limitations compared to native threads, subsequent Java versions dropped them in favor of native threads.
