Can you give a bit more detail on the kind of problem you're looking to solve? The Work Management API is a part of the connector spec and is primarily targeted towards system code that integrates with other systems. If you're looking for a way to add concurrency at the application level, there are alternatives. One is EJB 3.1, which supports simple asynchronous session bean invocations. That allows control to return immediately to the caller while the invocation is dispatched on a separate thread.
