TCP keepalives solve a different problem. Sure you can do read timeouts, but in the sync_client case, you could _theoretically_ have something blocking on a cyr_expire on a large folder of something that slows replication for a while - a read timeout will drop that connection even though the remote host is still "responsive". On the other hand, a TCP keepalive will tell if the remote host has actually gone away.
