Task.interrupt should work, though. Using vibe.core.concurrency it could also be made a bit shorter: 

@before!returnResponse("_res")
Data waitForUpdatedData(HTTPServerResponse _res, ...)
{
  auto parent = thisTid;
  Data result;

  auto disctask = runTask({
    try {
      _res.waitForConnectionClose();
      parent.send(false);
    } catch (InterruptException) return;
  });

  auto workertask = runTask({
    try {
      result = waitingForUpdates();
      parent.send(true);
    } catch (InterruptException) return;
  });

  if (receiveOnly!bool) disctask.interrupt();
  else workertask.interrupt();

  return data;
}

Thanks. This is exactly what I need.
