The problem, like I explained before, is that those are plugins and they are 
loaded to complement Qt functionality. Loading plugins is expensive, so they 
are kept loaded forever. Qt image plugins aren't expected to change, so we 
never unload them either.

They are only unloaded at the end of the application only.
