Original report:

Currently, Face will be put in "paused" state (canceled on outstanding async* operations).

When Face is used only to publish Data (e.g., example in note 2 of issue #1769), the pause condition is never satisfied and even if there is no incoming transmission is expected, async_recv is never stopped.

When Face is used to respond to exactly one incoming Interest (prefix unregistered just after data is "put"), it is unlikely, but the Face can be incorrectly and prematurely put to "paused" state with all send operations canceled.

I'm able to reproduce the first problem with an extension of the snippet given in note-6.

I'm unable to reproduce the second problem with this snippet:

Face face;
const RegisteredPrefixId* rpid;

void
processInterest(const Interest& interest)
{
  std::cout << "processInterest" << std::endl;
  KeyChain keyChain;
  auto data = make_shared<Data>(interest.getName());
  keyChain.sign(*data, signingWithSha256());
  face.put(*data);
  face.unsetInterestFilter(rpid);
}

int
main(int argc, char** argv)
{
  rpid = face.setInterestFilter("/C", bind(&processInterest, _2), bind([]{}));
  face.processEvents();
  return 0;
}

If you have a snippet that can reproduce the second problem , please report a separate bug, because these two problem are related but not the same.
