20  * Simple task executor interface that abstracts the execution
21  * of a {@link Runnable}.
22  *
23  * <p>Implementations can use all sorts of different execution strategies,
24  * such as: synchronous, asynchronous, using a thread pool, and more.
25  *
26  * <p>Equivalent to JDK 1.5's {@link java.util.concurrent.Executor}
27  * interface. Separate mainly for compatibility with JDK 1.3+.
28  * Implementations can simply implement the JDK 1.5 <code>Executor</code>
29  * interface as well, as it defines the exact same method signature.
