// clouds where a call to stop() would leave the machine running).

// However, there are still races. If the start() code has not yet reached the call to
// location.obtain() then we won't wait, and the start() call won't know to abort. It's
// fiddly to get that right, because we need to cope with restart() - so we mustn't leave
