Weird behavior with examples

[dagit]

I made a new project (cargo new --bin ctrlc_test), added ctrlc to my dependencies, and then copied the contents of simple.rs from this repo into my main.rs. Then I did a cargo build and ran the executable directly. It sits waiting for me to hit ctrl-c, but after I do that it prints "Hello world!" to the terminal until I kill it. This is on linux and using stable 1.3.0.

It seems like maybe once the handler is triggered it just runs forever?
