Comment 3 for bug 1326207

Just from reading the tracebacks above, the two issues I see are:

1) FlavorDiskTooSmall raised by driver.spawn() is going to result in a reschedule attempt which cannot succeed

2) In the exception handling of _build_resources() we do

                # Make sure the async call finishes
                if network_info is not None:
                    network_info.wait(do_raise=False)

    and get:

      'NetworkInfo' object has no attribute 'wait'

    We obviously expect it to be a NetworkInfoAsyncWrapper but it isn't for some reason.
