First, thanks to Lenny & the other folks who contributed to sysinfo.
It's a very handy little utility (BTW, I've replaced all previous
versions of sysinfo on osu-cis with the new version, and included
binaries to boot).

As far as the explanation goes, if the numbers have the same meaning
as in BSD, then they reflect the average over the last minute, 5
minutes, and 15 minutes, of processes eligible to run (in queue).
The one-minute figure gives you the strongest sense of dynamic system
load.  When the number climbs, more processes are contending for the
CPU, and thus turnaround time increases (so the system seems to get
slower).
