Recognizing the need to write reactor-based GUI applications, the ACE community has created several reactor extensions for use with X Window System. Each of these extends the ACE_Select_Reactor to work with a specific toolkit. By using these reactors, your GUI application can remain single threaded yet still respond to both GUI events, such as button presses, and your own application events.

Kokyu is a library designed to provide flexible scheduling and dispatching services.

Paste Deployment is a system for finding and configuring WSGI applications and servers. For WSGI application consumers it provides a single, simple function (loadapp) for loading a WSGI application from a configuration file or a Python Egg. For WSGI application providers it only asks for a single, simple entry point to your application, so that application users don't need to be exposed to the implementation details of your application.
