Ok, we need something that respects shared/nonshared. If 
aync/await involves multiple threads then we need something 

Maybe some runtime level thing that can offload computations but 
is as easy to use as await. Perhaps even offload to the GPU.

But I guess people want it for I/O.

Clearly a case where a library solution has to come first.

This should be possible with LLVM stop points.
