Aha! You win. I was using a PHP stats collector for interfacing 
Memcached to Cacti.

Indeed. Telnet says:

STAT rusage_user 5251.583637
STAT rusage_system 23525.710548

PHP script says:

    foreach ($result as $serverStats) {
        foreach ($serverStats as $statKey => $statVal) {
            if ($statKey == "rusage_user" || $statKey == "rusage_system") {
                $statVal = round($statVal * 1000);
            }
            echo "$statKey:$statVal ";
        }
    }

Thanks for the help with this. It'll make the Cacti graphs a bit more 
clear. To avoid doing much work here, I'll probably modify the PHP stats 
collector to do $statVal *= 1000000. It's losing 3 digits of precision 
with that round().
