This scares me, it seems to me that the unused import should not 
be compiled in. And I frequently hear people talk about the 
linker removing unused code, but this proves that it doesn't or 
at least not all.

I wonder if this is a matter of something that is possible but 
just not implemented properly(or at all, i don't know) in the 
linker, or if their is some reason that makes this not possible.
