This talk traces lightweight concurrency from Python 2.2's generators, which enabled semi-coroutines as a mechanism for scheduling "weightless" threads; to PEP 342, which created true coroutines, and hence made event-driven programming easier; to 3rd party libraries built around coroutines, from older GTasklet and peak.events to the current Greenlet/gevent and Twisted Reactor.
