Install more RAM cannot avoid such issue.

In the linux-kernel mailing list, people (Arjan, Jesper, and Dick)
pointed out that this is because of default overcommit policy. Setting
2 to /proc/sys/vm/overcommit_memory should solve this issue. I tried
it on my notebook, it works. The small test quits nicely. But on
uClinux, the process still got killed. I'm going to take a further
look.

Thanks,
