Good. Sounds like we are on the same page. We should be fine as long as it
doesn't happen very often. There will be time in 6.0 to clean it up,
upgrade Docker, and get rid of the issues.

Also, basic math rules apply. If it fails with 10% probability, you get 90%
(1.0-0.1) success on the first attempt. While the probability of failing
two times in a row is only .1*.1 = 1%, so the success rate after the second
attempt should be quite high.

Either way, I hope it won't be as frequent as 10%.

Thanks,
Roman
