This is exactly what background resolution does:
It starts Chrome early and closes late, so applications and extensions can have a longer life.
If any installed hosted application, packaged application, or extension has "background" permission, Chrome starts (invisibly) as soon as the user logs into his computer - before the user starts Chrome. Setting the background also forces Chrome to continue to work (even after closing the last window) until the user explicitly quits Chrome.
Just add "background" to the permissions specified in the manifest.json extension and it will continue to work until Chrome opens and after Chrome closes.
