Perform Actions need to be a queue and thread-safe.

[dravenk]

In the base release, of course, I marked unsafe handling for Perform actions.

// Perform an Action in a goroutine.
go action.Start()

Goroutine is not a queue. Not ensuring that actions are executed in order is the wrong way to handle multiple concurrent action requests. Channels are often used in Golang to handle communication or to implement a task queue. I plan is to create a runner similar to the Java version to execute actions.

    /**
     * Thread to perform an action.
     */
    private static class ActionRunner extends Thread {
        private Action action;

        /**
         * Initialize the object.
         *
         * @param action The action to perform
         */
        public ActionRunner(Action action) {
            this.action = action;
        }

        /**
         * Perform the action.
         */
        public void run() {
            this.action.start();
        }
    }
