Yup, I really need to fix this.  I haven't had much time recently w/ the way 
work has gone, but if I get the chance I'd like to do some major cleanups - 
including fixing this.  Let's see how the next few weeks go.

This hasn't been touched in a long while, I see. 
This could fix it at line 285.

It's a useful tool!

WAS:
        $outstats{cache_hit} = ( $stats{get_hits} / $stats{cmd_get} ) * 100;

FIXED WITH:
      if ( $stats{cmd_get} == 0 ) { 
        $outstats{cache_hit} = 100;
      } else {
        $outstats{cache_hit} = ( $stats{get_hits} / $stats{cmd_get} ) * 100;
      }
