cogen in the wild

[Matthew Scott]

I wanted to thank the contributors to Cogen for making such an awesome
kit!

cogen made it remarkably fun to port a select-based server to a
coroutine-based server.

Here's some client code that uses it:

It's a port of this code, altered to support multiple databases:

Are there any other Open Source examples of cogen in the wild that
folks are willing to share?
