Description

The current interface of the Subprocess only supports passing environment variables. It will be cool if we can support passing flags too:

Try<Subprocess> subprocess(
    const std::string& command,
    const Subprocess::IO& in, 
    const Subprocess::IO& out,
    const Subprocess::IO& err,
    const Option<flags::FlagsBase>& flags = None(),
    const Option<std::map<std::string, std::string> >& environment = None(),
    const Option<lambda::function<int()> >& setup = None());
