Description

PurgeQUeue does this while holding its lock:

        journaler.wait_for_readable(new FunctionContext([this](int r) {
          Mutex::Locker l(lock);
          if (r == 0) {
            _consume();
          }
        }));

But wait_for_readable does this:

  if (stopping) {
    onreadable->complete(-EAGAIN);
    return;
  }
