That's the side Microsoft took in the Windows 3.11 days - if a program
crashes your machine, that's not our problem - don't run the program.
If your machine is unusable, for anyr reason, what so ever, it's Linux's

I would be happy to go back to the 1.x days, where the machine would just
return -ENOMEM to programs that were looking for extra memory, and wouldn't
swap themselves unusable.
I've seen people with 256MB RAM running out of memory, and halting the
machine, from netscape over-caching...that's not on. I'll try out the OOM
patch, when I get a chance...
