I soft of feel like every five years someone comes along and tries to re-invent cancellable threads and immediately arrives back at the same conclusion: the problem of what it means to "cancel" a thread is so domain-specific that you never save anything trying to "support" it in your threading framework; you try and save people the effort of doing something ad-hoc to simulate cancellation and build something at least as complicated as what they would build ad-hoc, because thread cancellation is too intimately tied to the problem domain the threads are operating on to generalize it.

But what if we add another layer of indirection.
