> Currently, we always create a pipe when using subprocess. This is not desired in some cases. In some situation, we may just want the subprocess to inherit the file handles from the parent (or redirect to a file).
> We can mimic the Python subprocess interface to support those modes. The user can specify: PIPE, a existing file descriptor, or None for stdin/stdout/stderr.
> Try<Subprocess> subprocess(
>     const std::string& command,
>     const Option<int>& stdin = Subprocess::PIPE,
>     const Option<int>& stdout = Subprocess::PIPE,
>     const Option<int>& stderr = Subprocess::PIPE,
>     const Option<std::map<std::string, std::string> >& environment = None(),
>     const Option<lambda::function<int()> >& setup = None());
