I created python bindings for that asyncworker library. You can check it out here. Note that it does need some more love from an elite python hacker :-). I’m not a python hacker myself, so I had to learn from other libraries to get this binding correctly build.
It’s possible that I’ll do other such bindings like a C# one (since it’s fully GObject-style, this shouldn’t be hard to do). Meanwhile I kindly invite people to go ahead and get their bindings working in the subdirectory bindings. If you do, please leave it disabled from the build in the configure.ac (so like how the python-binding is configured a.t.m.). Most language-bindings (like a python-GObject binding) can be generated. So most of the times you don’t need to worry to much about API stability.
