Ummm, yeah, that would pretty much be the claim. Real easy to reproduce too. Take your favorite machine with lots of RAM, run just a handful of startup process and system daemons, then log in on a few terminals and do:
while true; do bonnie -s (1/2 ram); done
Pretty soon, system daemons will start to die.
