+ This kernel feature is useful for number crunching applications
+ that may need to compute untrusted bytecode during their
+ execution. By using pipes or other transports made available to
+ the process as file descriptors supporting the read/write
+ syscalls, it's possible to isolate those applications in
+ their own address space using seccomp. Once seccomp is
+ enabled via prctl, it cannot be disabled and the task is only
+ allowed to execute a few safe syscalls defined by each seccomp
+ mode.
+
+ If unsure, say N.
