It still not clear to we why the Process interface needs to be unrelated to
standard Java API like Callable? Why the following can't work?
public interface Process extends Callable {
void addListener(ProgressListener);
void removeListener(ProgressListener);
void cancel();
}
Keeping in mind that the Process can implement a cancel() operation without the
need to keep a reference to Future? i.e. it could just set a flag and the
working threads can break cleanly its inner loop when the flag is set, in the
same way than Image I/O:
