Initially I thought it might make sense to do that every callback probing but since the stats are per-program and they are shared between possibly several client callback instances, zeroing them out seems like the wrong thing to do. Note that that commit also introduced a bug since stats.program is also being cleared in the process and it is not restored after the memset as it used to be.
