Ah, okay, I was smoking something in my teens. Or maybe thinking of Kernel programming?? Anyway, in Linux, the man pages specifically states:
So develop_5889, don't use the alarm()/sigtrap routines -- just use sleep(). And actually, it makes more sense to call sleep() with the configured idle-time minus the amount of time that the TTY has been idle.

rwho
rwho(1) General Commands Manual rwho(1)NAME
rwho - Shows which users are logged into hosts on the local network.
SYNOPSIS
rwho [-a]
rwho [-a] [users]
OPTIONS
Includes all users. Without this option, users whose sessions are idle an hour or more are not included in the report.
DESCRIPTION
The rwho command displays the username, hostname, and start date and time of each session for everyone on the local network who is cur-
rently logged in to a host running the rwhod daemon.
If one or more user names are specified, only the status of those users whose names are listed appears on the screen. If a user has not
typed anything for at least 3 minutes, rwho reports the idle time as a number of minutes in the last column. After an hour of inactivity,
a user is not included unless the -a option is specified. Because this command displays a lot of output, use this command with caution if
the local network has a large number of users.
Status information is broadcast once every 3 minutes by each network host running the rwhod daemon. Any activity (such as a user logging on
or off) that takes place between broadcasts is not reflected until the next broadcast.
EXAMPLES
To get a report of all users currently logged into hosts on the local network, enter:
$ rwho
