Coroutines and threads are different. Look at the manual for a good
introduction.

As for vala async support, I tried using it. When you have a
more-than-banal scenario it's a mess.
Especially if you want to implement a custom scheduler. Say you want
to be able to pass the schedule to a specific task (such as for a
generator).

Async support in vala is just not meant to provide generic support for
coroutines.
