This is implemented by re-execing /proc/self/exe (typically)
- with right parameters. Some selected applets ("NOFORK" applets)
- can even be executed without creating new process.
- Instead, busybox will call <applet>_main() internally.

- However, this causes problems in chroot jails without mounted /proc
- and with ps/top (command name can be shown as 'exe' for applets
- started this way).
-# untrue?
-# Note that this will *also* cause applets to take precedence
-# over shell builtins of the same name. So turning this on will
-# eliminate any performance gained by turning on the builtin "echo"
-# and "test" commands in ash.
-# untrue?
-# Note that when using this option, the shell will attempt to directly
-# run '/bin/busybox'. If you do not have the busybox binary sitting in
-# that exact location with that exact name, this option will not work at
-# all.
