After having firefox killed by the OOM-killer due to a totem running
(and watching the killer churn the disks for 5 minutes to do so, what the heck
is it doing?), I ventured to try a hard overcommit limit (which setting
vm.overcommit_memory=2 does, to the best of my knowledge). The system in
question has 640MB RAM, no swap.
Running completely without swap is know to be dangerous..
