It is entirely possible that this is related to your particular Windows installation. If you've only tried threading-based solutions, then it is possible that the memory limitations are directly responsible for this... > I have seen details of "tasklets", "greenlets", but no code samples and/or > anything that seems to work. Umm, okay. Well, as you are most likely aware, tasklets and greenlets are primitives which relate to control flow. Greenlets like coroutines, and tasklets like microthreads. In terms of scalable IO, they are merely useful to wrap asynchronous IO in a way that doesn't necessarily require layers of abstraction and boilerplate. However many connections you could support using them would be comparable to however many you could support using other frameworks that adopt asynchronous IO based solutions. i.e. Twisted, asyncore, ... > Does anyone know of something that WILL work, even a simple TCP server will > do to test with.

If you wish to try an asynchronous IO solution assisted by the use of Stackless, you might check out the networking example code in the Stackless examples project: http://code.google.com/p/stacklessexamples/wiki/StacklessNetworking The most directly relevant example might be the chat server: http://stacklessexamples.googlecode.com/svn/trunk/examples/networking/chatServer.py In it, you can see standard socket usage transparently using the 'stacklesssocket' module and therefore asynchronous IO within the microthreading.
