> the collection returned by getChannels() may be modified by other threads, leading to unsafe iteration throwing ConcurrentModificationException.
> The returned object should instead be a copy of the data and the underlying map should use a thread safe implementation to allow for the safe copying of the values() collection while another thread may be modifying the map.
