 * I am struggling with performance. When I activate Multiple Post Thumbnails plugin
   and hit refresh on my web, Goggle Renderer is running 100% CPU, FF is about 30%,
   but it drops instantly when I deactivate the plugin and refresh.
 * Don’t really understand why. I tried to debug it, strip all JS, profile JS in
   browser, but haven’t found any indication of particular problem. Have anyone 
   coma across this issue?
