## Title

    Missing executable is reported on the ChildProcess error event

## Body

    When child_process.spawn receives a command that cannot be resolved, the call can return a ChildProcess before the failure is delivered. Attach an error listener immediately and handle error code ENOENT; do not rely only on synchronous exceptions or the close event.
