  1595. kexec is a system call that implements the ability to shutdown your
  1596. current kernel, and to start another kernel. It is like a reboot
  1597. but it is independent of the system firmware. And like a reboot
  1598. you can start any kernel with it, not just Linux.

  1610. This kernel feature is useful for number crunching applications

  1613. the process as file descriptors supporting the read/write
  1614. syscalls, it's possible to isolate those applications in
  1615. their own address space using seccomp. Once seccomp is
  1616. enabled via /proc/<pid>/seccomp, it cannot be disabled
  1617. and the task is only allowed to execute a few safe syscalls
