You can "fix" that problem by using
ClientAliveInterval 60
ClientAliveCountMax 2

on /etc/ssh/sshd_config

This means clients will be disconnected after 2 tries, spaced by 60 
seconds each.

I have tested this and many other login.conf options, such as idletime 
and maximum session times, it seems that these values do nothing, and as 
far back as I can remember (4.4-RELEASE), they never did. Either I've 
been doing something wrong all this time, or they really don't work :)

A more direct answer to your problem (depending on what you're trying to 
solve, if it's just hung users on the 'w' output, the above suggestion 
will fix that) might be sysutils/idled, which is a daemon that does just 
what you want.
