man sshd_config says KeepAlive is enabled by default. The commented-out
entry in sshd_config is:

#KeepAlive yes

Looking at some other entries I guess these represent the defaults
according to the man page. Is there any reason not to trust that sshd
has KeepAlive enabled by default?

Is KeepAlive an issue at all, if the link is not subject to disruption?
