CLI hangs on "generating results..."

[paulirish]

with what's on master:

lighthouse --perf "chrome://version" --output=json > file2.json

Just hangs there indefinitely until this error:

(node:49615) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): Error: The asynchronous expression exceeded the allotted time of 60s
(node:49615) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Hmmm, interesting latest master for me doesn't hang or crash, but there's a 50/50 chance of timing out on waiting for the page to load. Might be related to waiting for CPU idle?

Well of course now I can't get it to timeout anymore. Looks like we're missing more DOM.enable calls though
