Is this the cfluffy you wanted? [y/N] y
Permanently track this user, and write proof to server? [Y/n] Y

... aand, that’s all folks, never comes back. I interrupted and tried a restart, no change.

Quite possibly intermittent 1-time problem, but hey.

Start by reproducing `keybase track cfluffy` with the shown identity-proof output and the described unreliable Internet connection. Trace the tracking command after confirmation and determine why it does not return; done means the command completes or reports a bounded error instead of hanging.
