/**
* Simple task executor interface that abstracts the execution
* of a {@link Runnable}.
*
* <p>Implementations can use all sorts of different execution strategies,
* such as: synchronous, asynchronous, using a thread pool, and more.
*
* <p>Equivalent to JDK 1.5's {@link java.util.concurrent.Executor}
* interface; extending it now in Spring 3.0, so that clients may declare
* a dependency on an Executor and receive any TaskExecutor implementation.
* This interface remains separate from the standard Executor interface
* mainly for backwards compatibility with JDK 1.4 in Spring 2.x.
