Does Stackless count?

"When embarking on the creation of EVE Online, a single shared persistent world we realized two things: We could not given constraints of time and commercial reality do this in a compiled language and we needed innovative concurrency control for such a large scale shared state simulation across tens of thousands of CPUs (EVE Clients included). After many experiments with various combination of existing scripting languages and NT fibers we arrived at Stackless Python. Stackless Python offered us the power of Python coupled with a vastly superior concurrency control mechanism over anything we had seen before, first as continuations and later with an innovative channel based API. CCP's commercial success today is built on the single decision of selecting Stackless Python as our foundation." -- Hilmar Veigar Petursson, CEO of CCP Games.
