It's just a fancy thread pool/task queue with a fugly syntax extension not some magic unicorn that poops rainbows. Java/C# don't need a language extension - the functionality exists outside the semantic boundary of the language. Another cludge in Objective-C. C# (ThreadPool/async framework/Windows workflow) and Java (ExecutorService/lots of 3rd party frameworks) have had them for years with well-known communication, thread safe data structures, concurrency and locking semantics. Most of the verbose mess you see in Java threads is because the person writing it doesn't know much.
