* util-linux kill implementation is used in many distributions

 * the latest active procps upstream (fork at http://gitorious.org/procps/

)
   does not build kill(1) by default

 * util-linux implementation is actively improved and we follow Linux
   kernel features (e.g. RT signals, sigqueue(2) support, ...)

 * kill(1) is basic command without dependence on /proc, it does not make
   sense to have it in procps package.

... so it does not make sense to mark deprecate this code.
