[dhgex.sh integrity.sh kextype.sh rekey.sh try-ciphers.sh]
     repair regress tests broken by server-side default cipher/kex/mac changes
     by ensuring that the option under test is included in the server's
     algorithm list

      this test is a sorry mess of race conditions; add another sleep
      to avoid a failure on slow machines (at least until I find a
      better way)
