This is very simple if the branching factor is 10000

I believe that at big depth the branching factor can be huge.
I remember cases of branching factor of more than 100 with other
programs(including fruit) when the depth was clearly smaller than 30.

The fact that task manager shows that rybka continues to work strongly suggest
that rybka has no limit of 30 plies.
