roseus is left as zombie process even `rosnode kill`-ed

[furushchev]

I use ros::spin to spin ros service like followings:

;; sample.l
(ros::roseus "foo")
(ros::spin)

<launch>
  <node name="sample" pkg="roseus" type="roseus" args="$(find bar_pkg)/sample.l"/>
</launch>

However when I run rosnode kill /sample to kill the roseus process, it is ignored.
(Actually, /sample is removed from rosgraph, but the process still exists as zombie process)
