True. I didn't actually realise the Nimrod implementation was garbage collected, I just assumed for some reason it managed memory in a hidden manual way like the C++ implementation. Note that garbage collection may not actually occur in this benchmark; for the single threaded benchmark at least, the Go runtime didn't make a single call to the GC, so D and Nimrod might be similar.
