+# test_ssl: Don't stop ThreadedEchoServer on OSError in ConnectionHandler
+#
+# If `read()` in the ConnectionHandler thread raises `OSError` (except `ConnectionError`),
+# the ConnectionHandler shuts down the entire ThreadedEchoServer,
+# preventing further connections.
+# It also does that for `EPROTOTYPE` in `wrap_conn`.
+#
+# Make sure that the context manager *is* used, and remove the `server.stop()`
+# calls from ConnectionHandler.
