This is a great thing.  Sorry I didn't notice this patch earlier.  Let's polish it up and land it.

This is a bad pattern I think we shouldn't expand upon.  Capture protectedThis = makeRef(*this) to make sure this isn't deallocated underneath us while waiting for the lambda to be called on another thread.

Issac is this something you're going to complete? If not could you let us know so we can assign someone over to take a look?

Hi Don, Sorry I'm not working on this anymore, feel free to take this over.
