+        # this test works like this:
+        # - use curl to POST data to the server /h2test/echo
+        # - feed curl the data in chunks, wait a bit between chunks
+        # - since some buffering on curl's stdout to Python is involved,
+        #   we will see the response data only at the end.
+        # - therefore, we enable tracing with timestamps in curl on stderr
+        #   and see when the response chunks arrive
+        # - if the server sends the incoming data chunks back right away,
+        #   as it should, we see receiving timestamps separated roughly by the
+        #   wait time between sends.
