because in my case, 99.9% of all games played have ponder=on.  I only disable
pondering to debug so that I can reproduce the same searches over and over
when necessary.  Since almost all real games are played with ponder=on, I don't
have a special time-allocation formula for ponder=on and another one for
ponder=off.  I just have one that _assumes_ ponder=on.

I see no reason to waste what little time I have working on something that is
hardly going to be used...
