top from the command line, the process
GTK-gnash always showed up usually with three instances of it.
Killing it didn't seem to make much difference, it just reappeared again, and the killed ones became zombies. So, how to
get rid of it?
The answer is to use apt-get to remove
gnash which is a GNU Shockwave Flash [swf] player. This also removes
browser-plugin-gnash. As I don't like watching flash programs/videos it was an easy decision to get rid of it.
sudo apt-get autoremove also removes the following orphan files -
gstreamer0.10-fluendo-mp3, libboost-date-time1.42.0, libboost-thread1.42.0, but I've yet to see any benefit of
removing them, except to get rid of unused files.
