I agree with @ianswett that this is a transport issue, and doesn't belong in the recovery document. There we are only talking about the timers needed for loss recovery, and I would find it confusing to talk about closing connections there.
I'm not sure if we need to have any text about a handshake timeout. An idle timeout should be sufficient to garbage-collect connections that aren't active any more. Having a (shorter) handshake timeout is an optimization that implementations might or might not want to have, depending on the threat model.
