one or two pings dropped with Reactive Fwding app and pingall

This seems like it is a performance issue as a second pingall is 100% successful

Example output with a 3x3 torus:

• • • Ping: testing ping reachability
      h1x1 -> h1x2 h1x3 h2x1 h2x2 X h3x1 h3x2 h3x3
      h1x2 -> h1x1 h1x3 h2x1 h2x2 h2x3 h3x1 h3x2 h3x3
      h1x3 -> h1x1 h1x2 h2x1 h2x2 h2x3 h3x1 h3x2 h3x3
      h2x1 -> h1x1 h1x2 h1x3 h2x2 h2x3 h3x1 h3x2 h3x3
      h2x2 -> h1x1 h1x2 h1x3 h2x1 h2x3 h3x1 h3x2 h3x3
      h2x3 -> h1x1 h1x2 h1x3 h2x1 h2x2 h3x1 h3x2 h3x3
      h3x1 -> h1x1 h1x2 h1x3 h2x1 h2x2 h2x3 h3x2 h3x3
