There is, of course, yet another alternative: Write a TaskLocal(T) class, like we did, that bases the storage on the current Task, rather than the current Thread. Honestly, I have no idea why Microsoft didn't do this as part of their initial Task implementation.

Important Implementation note: Because Task code that calls await can be split, and resume as a different TaskId, you also need to do what we also did, and implement a method in TaskLocal(T) that maps new TaskIds to previous ones, then save the original TaskId at the start of the Task, and map it after every await call.
