This is where I frequently have found problems with sharpening. It's not the 
completely out of focus stuff that is a problem. For lack of a better term, 
partially unfocused areas give sharpening software grief.
What buggers things up is when you have a partially unfocused background and 
you hit the entire image with USM.
Quite often, I am finding that what was a nice background suddenly has 
double image (bokeh) simply because it wasn't out of focus enough and USM 
had enough to work with.
