Message passing between threads: Java 4 times faster than D

So a queue per message type? How would ordering be preserved? Also, how would this work for interprocess messaging? An array-based queue is an option however (though it would mean memmoves on receive), as are free-lists for nodes, etc. I guess the easiest thing there would be a lock-free shared slist for the node free-list, though I couldn't weigh the chance of cache misses from using old memory blocks vs. just expecting the allocator to be fast.
