How long a connection must survive before a later drop starts the reconnect
ladder over from the base delay.
Resetting on connect instead would be wrong in the case that matters most: an
intermediary that admits the handshake and then severs the connection would
produce connect, reset, sever, retry at one second, forever. Judging the
connection at the moment it drops separates a genuine recovery from a flap.
