I use this approach extensively, using tasks which are defined using generators. The scheduler I developed for this can be viewed here:

http://metaplay.dyndns.org:82/svn/nanothreads/nanothreads.py

Synchronization using yield statements is an important feature, as I use these cooperative threads for game development. These threads are very useful for games, as they have very low overhead, and allow the programmer to exercise more control over their execution.
