Now:

    Make writes to /dev/console appear on DEVICE (default: /dev/tty).

Denys Vlasenko 5c527dc57e make 17 state-changing execing applets (ex: "nice PROG ARGS") noexec 
The applets with "<applet> [opts] PROG ARGS" API very quickly exec
another program, noexec is okay for them:

 chpst/envdir/envuidgid/softlimit/setuidgid
 chroot
 chrt
 ionice
 nice
 nohup
 setarch/linux32/linux64
 taskset
 cttyhack

"reset" and "sulogin" applets don't have this form, but also exec
another program at once, thus made noexec too.

$ echo $$

$ echo $$
18448
$ echo $? <wait here, run "kill -INT 18448" in other shell><press enter>
^C
