   tests with markers=keep & delete all good other than
   * continuous read() under-fulfillment breaking tests which expect their buffers to always
be full. Root cause clearly some networking issue, but where?
   * ITestS3AInputStreamPerformance stream had to be reopened 3 times, rather than 1. Didn't
come back on a rerun.
