We have enough failures these days; getting timed out when tests are
almost done is the last thing we need :)
On avg. the Linux integration tests are taking 15-17 min, but sometimes
they end up at 20 or a bit over and get canceled. I've seen rare cases
where the Vagrant setup+build+test runs gets very close to 40 min as
well.
