 * Put a dummy task into the queue and wait for it to be run. Because it's single threaded, this means all

 * convenience primarily used in unit testing. If you want to wait for an event to be called the right thing
 * to do is usually to create a {@link com.google.common.util.concurrent.SettableFuture} and then call set
 * on it. You can then either block on that future, compose it, add listeners to it and so on.
