> In theory the key event is "server receives the client Finished message", which the server sees directly, and the client notices when the Finished message is acknowledged.

The ACK for that could be lost. The client will then start the handshake timer and keep retransmitting the Finished, until it receives an ACK (assuming that the server keeps the keys around for long enough, which it currently doesn't, see #2267).
