Subject: [PATCH] test: ensure that all worker servers are ready
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wait for the `'listening'` message from all workers before creating the
first connection. This fixes an `EMFILE` error that is raised on Windows
when running the following command

```
python tools/test.py -J --repeat=1000 parallel/test-tls-ticket-cluster
```
