If I'm not mistaken, CCP "porkbelly" on the forums is Kristján. Quoting him:

"Meanwhile I´ll offer that StacklessIO is a framework that allows us
to make things such as asynchronous IO and work that is spawned off to
worker threads appear as regular, blocking operations for tasklets in
Stackless Python. We then use this to perform asynchronous Winsock
operations using IO completion ports. The semantics are not new, but
the scheduling framework and the lightweight winsock layer we use
are."

I.e. it is similar to what we have been discussing here for very long,
except only for Windows I guess.

cheers,
