You can write a custom reactor. For an example, take a look at the gtk2 reactor, http://twistedmatrix.com/trac/browser/trunk/twisted/internet/gtk2reactor.py#L146 > Eventlets look promising because it is implemented using coroutines without > an explicit event loop call, instead the event loop is run transparently when > required.

I came across this stackless example for Twisted, http://www.imperialviolet.org/binary/st.py I don't know how mature is Twisted's stackless support. > I have been evaluating twisted for sometime for doing this, but I have not > been able to wrap my brain around twisted. .. around *yet*. Speaking from my experience, it is only a short term struggle - once you become a little comfortable with the feel it, Twisted programming becomes a joy in itself. When I was learning Twisted, the knowledge of its component system helped a lot, http://twistedmatrix.com/projects/core/documentation/howto/components.html I also noticed that Eventlet seems to support Twisted, although it is currently broken: > twistedsupport.py : Support for using eventlet with twisted.
