Safe reference counting cannot be implemented as a library

  I did a rough check of the Rust compiler source(from a copy I 
downloaded a couple months ago).

I think the compiler is supposedly filled with old code, not sure 
if it is the best example of Rust.

  I filtered out the rc/arc.rs files, and doc/test folders

  Some of these hits were comments/commented out, but I'm too lazy 
to bother removing them

Anyway:

Searching 7524 files for "Rc::new(" (case sensitive)

122 matches across 49 files

Searching 7524 files for "Arc::new(" (case sensitive)

60 matches across 28 files
