Can we fetch the json even before calling Runtime.startApplication, and here
just eval it? We'll avoid any intrusion into Runtime.

[lushnikov, 2016/07/07 21:26:22]

Done.

Annotate the url.

[lushnikov, 2016/07/07 21:26:22]

response.text() is a promise

I'd like to leave this as step-by-step as it doesn't impact performance but
makes reading easier
