I re-post my comment: 

Hi! I was wrong on the correction. The problem was when all of the threads were 
busy. 
This fixed the code:

protected NotificationThread getNextAvailableThread() {
        for (int i = 0; i < threads.size(); i++) {
            NotificationThread thread = getNextThread();
            boolean busy = thread.isBusy();
            if (!busy) return thread;
        }
        return getNextThread(); /* All threads are busy, return the next one regardless of its busy status */
    }

    /**
     * Get the next thread to use.
     * 
     * @return a thread
     */
    protected NotificationThread getNextThread() {
        if (nextThread >= threads.size()) nextThread = 0;
        NotificationThread thread = threads.get(nextThread++);
        return thread;
    }

Judging from the original post, this issue still exists in 2.1.1?

Issue 85 states that it was fixed in r338.  Have you tried the latest build?

Make sure you try the latest BUILD, not just the latest released version....  
See the Requirements wiki page for info about nightly builds.
