+ # 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.
