Considering that the error returned is -ECONNREFUSED, this is a
reasonable assumption, yes.

On a normal system, the tests pass fine, and it would be a bug if they
Did you look at the `tor_ersatz_socketpair()` code at all? It should
be obvious why this is failing on Tails.

* Don't use Tails, the tests are written under the assumption that
they are running on a normal system that doesn't have a facist
firewall preventing connections to things listening on the loop back
* Patch the test code to disable that test.
* Maybe use torsocks with "AllowOutboundLocalhost", if the version
included in Tails supports the option (I'd hope so, I added support
for that feature to torsocks specifically for them). Other tests may
or may not fail if you chose to go down this path.
