Merge remote-tracking branch 'public/ticket28838_035' into maint-0.3.5

  o Minor features (performance):

    - Remove about 96% of the work from the function that we run at

      startup to test our curve25519_basepoint implementation.  Since

      this function has yet to find an actual failure, we'll only

      run it for 8 iterations instead of 200. Based on our profile

      information, this change should save around 8% of our startup

      time on typical desktops, and may have a similar effect on

      other platforms.  Closes ticket 28838.
