Please mark flaky tests as "Pass,Fail". This way we at least catch crashes.

I'll leave it to your team to make adjustments to the status file.

My goal is to make the build bots green with as little use of skip as possible.
However, once I have failed getting the status right for a particular test, I
play it safe and use skip. This is because I'm trying to maximize my chances
that the 45 minute build bots remain green.
