603 kexec is a system call that implements the ability to shutdown your
604 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400605 but it is independent of the system firmware. And like a reboot

652 This kernel feature is useful for number crunching applications
653 that may need to compute untrusted bytecode during their
654 execution. By using pipes or other transports made available to
655 the process as file descriptors supporting the read/write
