Not much better, probably worse, given that Go has stack 
protection for fibers and D doesn't. So in Go you can get away 
with 2K growable stacks, in D you would need a lot more to stay 
on the safe side.

IIRC he claims that CPython would  fast enough for their 
application and that the application was memory limited and not 
computation limited.
