I'm a little worried you have no volatile writes or fences around your code when you 'publish' an event using head/tail etc. It looks like it's working but how are you ensuring no compiler/CPU reordering is ocurring. Does x86_64 actually allow you to get away with this? I know its memory model is stricter than others...

I just add atomic fence for push and take:

                this.messages[ this.tail ] = value;
                atomicFence;
                this.tail = ( this.tail + 1 ) % this.size;
