Subject: [PATCH] Duplicate frozen CHILD_STATUS to allow rspec proxy

Without this, a test fails because rspec is unable to proxy $CHILD_STATUS/$?. I looked around for another way to handle this but there's no way to unfreeze except through duplication.

```
1) Bundle when the system call fails emits all stdout output even if verbose is false
     Failure/Error: success = st.success?

     ArgumentError:
       Cannot proxy frozen objects, rspec-mocks relies on proxies for method stubbing and expectations.
