Unhandled rejection reported by thinky/rethinkdbdash when db host is not running

[lillereven]

During testing I chanced upon this:

Unhandled rejection ReqlDriverError: None of the pools have an opened connection and failed to open a new one.

This is using thinky 2.2.4 w/ rethinkdb 2.2.3-1

[neumino]

Hum, this is working as intended, though maybe we should call process.exit(1) What happens here is that we can't actually create the database, so from there we can't make sure that anything will work.

[neumino]

It's definitively not optimal though.

[lillereven]

True, it's not optimal. Would it be possible to let the error bubble so the app has a chance to log stuff and retry? That way the app could recover when the DB comes back online.

@lillereven -- You can try this comment and you can prevent the driver from writing to stderr by passing silent: true
