Examples of PoolExecutor

com.opengamma.util.PoolExecutor
Implementation of {@link Executor} that allows jobs to run in a group with a single consumer receiving results for them.
The maximum number of additional threads is limited, but the thread which submitted jobs may temporarily join the pool to allow its tasks to complete.
org.simpleframework.util.thread.PoolExecutor
The PoolExecutor object is used to execute tasks in a thread pool. This creates a thread pool with an unbounded list of outstanding tasks, which ensures that any system requesting a task to be executed will not block when handing it over. @author Niall Gallagher
