115 help
116 This kernel feature is useful for number crunching applications
117 that may need to compute untrusted bytecode during their
118 execution. By using pipes or other transports made available to
119 the process as file descriptors supporting the read/write
120 syscalls, it's possible to isolate those applications in
121 their own address space using seccomp. Once seccomp is
122 enabled via /proc/<pid>/seccomp, it cannot be disabled
123 and the task is only allowed to execute a few safe syscalls
124 defined by each seccomp mode.
125
126 If unsure, say Y. Only embedded should say N here.

235 overhead. However the utilization of memory will increase.
