spin/spinOnce/etc. only affect calling your callbacks. Publishing a message
does not require spin/spinOnce at all. (Mentioned briefly in the pub/sub
tutorial:
http://www.ros.org/wiki/roscpp_tutorials/Tutorials/WritingPublisherSubscriber,
and more in-depth in the callbacks/spinning overview:
http://www.ros.org/wiki/roscpp/Overview/Callbacks%20and%20Spinning).
