Many concurrency systems provide for external cancellation. One way to approach this would be to allow exceptions to be thrown into running code from outside. There could be flavors of these, like "nobody is interested in your .result anymore, just complete any side-effects" One might also want a more polite a "throw this exception into this thread, but only if the thread has defined a handler for it."
