Well, I find it an interesting option to give to users - if you need
the faster convergence, but can live with half the lookup rate, it's
nice to *have* the option.  (Our 6500s peak at well below 10Gbit/s
throughput, so we could easily affort to half top pps if we wanted to 
do use PIC - but the increased memory usage is what keeps us from 
doing so)
