I thought this conversation had been had in the past, but I can not find it
so forgive me if I'm rehashing something thats been discussed already.

How do you guys detect dead peers?  Actively via a ping or passively via
the 'latest handshake' (once it gets past a certain age, you assume the
peer is offline).  Are their other options?
