I think we should pass the wait time in here, too, with no retries.

Done.

Why wait_time/2?

[tonyg, 2014/07/08 20:17:10]

Since we'll run this twice (1 retry), I initially thought each should get half
the time. But upon further thought, that doesn't make a lot of sense, so I just
made it wait_time.
