> All syscalls except whitelisted ones will cause SIGSYS.

> We test the sandbox with BPF_TEST and BPF_TEST_DEATH, which appropriately fork the process so the main process of the test will never enable the sandbox.

> TEST=Build chrome and nacl_helper on i686, x86-64, and ARM 
> TEST=./out/Release/components_unittests --gtest_filter='NaClNonSfi*'
>      # on i686, x86-64, and ARM
> TEST=SFI NaCl apps still work
