Overview

Note:

When running on the JVM (JRuby) this class will inherit from JavaFixedThreadPool. On all other platforms it will inherit from RubyFixedThreadPool.

A thread pool with a set number of threads. The number of threads in the pool is set on construction and remains constant. When all threads are busy new tasks #post to the thread pool are enqueued until a thread becomes available. Should a thread crash for any reason the thread will immediately be removed from the pool and replaced.

The API and behavior of this class are based on Java’s FixedThreadPool
