* An asynchronous execution interceptor for methods returning {@code void}. Because asynchronous invocations
* necessarily run in a concurrent thread, any thread context setup interceptors should run <b>after</b> this
* interceptor to prevent that context from becoming lost. This interceptor should be associated with the client
* interceptor stack.
*
* This interceptor should only be used for local invocations.
