@pjweinb can we please make this test astronomically un-flaky?

[pjweinb]

sure. the easiest way would be to remove it altogether. For, after months of running it it seems ok. Alternatively we can up the 4.5 to some larger number, and reduce the flake rate to expect one a century [but it might happen tomorrow and again the day after].

Either seems fine to me.
