A parallel, non-concurrent, thread of execution.
It should be able to transfer control from arbitrary places in 
execution, not within generators.

Stackless provides coroutines. Greenlets are also coroutines (I think).

Lua has them, and is implemented in ANSI C, so it can be done portably.
See: http://www.jucs.org/jucs_10_7/coroutines_in_lua/de_moura_a_l.pdf

(One of the examples in the paper uses coroutines to implement 
generators, which is obviously not required in Python :) )

Cheers,
Mark.
