Cap nAttempts penalty at 8 and switch to pow instead of a division loop.
On hosts that had spent some time with a failed internet connection their
nAttempts penalty was going through the roof (e.g. thousands for all peers)
and as a result the connect search was pegging the CPU and failing to get
more than a 4 connections after days of running (because it was taking so
long per try).
