SO_KEEPALIVE isn't useful here, it will detect dead connections only
after hours which is way too much.

leafnode has already been using its internal mgetaline() function when
expecting a server reponse with status code which timed out after 15
minutes, but didn't - before 1.9.52.rc1 - use that function to read the
payload. Such changes are still pending for leafnode-2.
