Reported by Vegard Nossum: "I found this program lying around on my
laptop. It kills my box (2.6.35) instantly by consuming a lot of memory
(allocated by the kernel, so the process doesn't get killed by the OOM
killer). As far as I can tell, the memory isn't being freed when the
program exits either. Maybe it will eventually get cleaned up the UNIX
socket garbage collector thing, but in that case it doesn't get called
quickly enough to save my machine at least."
