Comment 1 for bug 2024926

Note that this was due to a very specialized kind of outage, namely where the machine-readable API description file fetched from api.launchpad.net refers to api.launchpad.test (which only exists in some development setups and shouldn't be referred to from production). This part of the problem was on us (the Launchpad team), and we've fixed it.

It's also a little surprising, since we had other reports of clients (including at least one that was also running Ubuntu 22.04) instead raising the rather clearer `httplib2.error.ServerNotFoundError: Unable to find the server at api.launchpad.test` (still a bit confusing of course, but it points to the problem about as well as it can). I don't know why `socket.getaddrinfo` would raise `EBUSY` in this case, though.
