Concurrency Options on the JVM
summary
Contains concrete details: which thread pools (single, cached, fixed, ForkJoinPool), how to set keepAlive and daemon threads, when to call shutdown and awaitTermination, and the danger of pool-induced deadlock when a bounded pool blocks on work that needs the pool. Covers Executors.newCachedThreadPool/newFixedThreadPool, ForkJoin common pool behavior, Scala akka actors, Clojure core.async, Futures vs CompletableFuture, jstack for diagnostics, and always use timeouts.
