Right now, the polling mechanism prints 2 lines for every poll. Like the following:
Waiting for remote build to finish.
Waiting for 10 seconds until next poll.
Waiting for remote build to finish.
Waiting for 10 seconds until next poll.
Waiting for remote build to finish.
Waiting for 10 seconds until next poll.
Waiting for remote build to finish.
Waiting for 10 seconds until next poll.

In my opinion, there are no needs to print polling information at all (at least by default), if the polling was successful. There could still be a message from time to time, if the number of polls until the job ends seems high.
I know that you can configure the polling time, and increasing it would reduce this problem.
