thanks!

well
- even on small disk it's easy to go over 10 seconds (I've seen android devices taking over 30 seconds on devices with 16GB of disk)
- having to retry sometime is a no go, we don't want flacky tests
- we need to design the tests to be robust on any device, not just to work on a new install in the QA test config
