If you add some magic to the coroutine code, I'd rather that it works on
all situations... Ie if in the future we create a GTask in the main
context, return from coroutine context, but have no code which is going
to switch coroutine state, what is going to happen? is your added
coroutine magic going to fail over? Do we already have some API in the
coroutine code which have these expectations? (if you use this, trigger
a coroutine switch before next idle is dequeued?)
