Re: oil leak behind the accessory belt & pulleys

Related note, when I was changing the belt tensioner pulleys, which required removing the tensioner assembly, one of the (very long) bolts holding it onto the block had engine oil on it. Had to be very careful not to get any on the belt or pulleys.
Are these holes used when casting the block or is there some other reason that the engine designers chose to have a bolt hole go right through to an oil gallery?
