Well, this matches rather well the 8800 also :-) It is the same feeling
when ftp.luth.se needs to be restarted. Because of its stability; this
normally only happens after a power outage and because some of the 50-60
RA9x disks on it have died :-)
VMB on it takes 40 minutes to check 512MB of memory...
