Checks whether some operation has been cancelled; This will typically
be used as a callback because it can only query whether a task has
been cancelled, rather than cancel it (there is no cancel() method).
(The name Cancelable kinda seems to imply that there is only a
void cancel() method, so maybe this interface should really have a
different name - any ideas?)
