I start with 256M and eat it up with programs until there is only about 7 megs left, no swap. From that point all user processes stall and the disk begins to grind nonstop. It will continue to grind for about 25-30 minutes until it goes completely silent. No processes get killed, no VM messages are emitted. The only recourse is the magic key. If I reboot before the disk goes silent I can cleanly kill X with sysrq-E and restart. If I wait until it goes silent, all is lost. I have to sysrq-SUB. Note, I do not have ANY swap enabled for these tests.
