As for me, async/await feature is a half-baked solution. With

at all. Details: http://vibed.org/features

It starts automatically when you try to allocate memory and there 
is no space in heap. In fact, it leads to architecture 
restriction: destructors must be @nogc. Also, you can run it with 
GC.collect()

Yes.
