You want to use an errordomain, not instantiate your own GLib.Error. As you
said earlier, this is a non-GLib library. It probably shouldn't be throwing
GLib errors.
I've dealt with this when writing code with a non-GLib library (Sqlite),
trapping its error codes, and then throwing exceptions
There is limited support for autotools. Valencia can detect your project

Yes, your closure isn't being called until some time after get_results()
returns.
Remember, async works with the event loop. A good way to think of it is like
this: some_async_method.begin() doesn't call the method, rather .begin
schedules the method on the event loop for later execution.

For async to work properly, you must run the GLib MainLoop. MainLoop is where
your async closure for test_function.begin() is called. It's where all
callbacks are scheduled, actually.
The only reason this works is that in the case of DO_YIELD you stash the
test_function.callback and then
called even without a main loop :?
Thanks!
