[cherrymui]

There are more flaky failures on this since June 20, https://ci.chromium.org/ui/test/golang/cmd%2Fcgo%2Finternal%2Ftestcarchive.TestManyCalls?q=V%3Abuilder%3Dgotip-linux-amd64-longtest-test_only+V%3Ago_branch%3Dmaster+V%3Agoarch%3Damd64+V%3Agoos%3Dlinux+V%3Ahost_goarch%3Damd64+V%3Ahost_goos%3Dlinux
which were matched to #61069.

Tentatively mark as a release blocker, as the high-rate flaky failures seem to start recently.

I pulled the test timing data from LUCI.

So it seems the test timing was pretty steadily <20 seconds, then it starts rising since d881ed6, up to 180ea45 which is 50+ seconds. At afbbc28 it drops back to mostly <30 seconds (with few exceptions), until d79c350 it rises again.

For the first elevated period, as afbbc28 is a revert of d881ed6, it is likely that d881ed6 is the cause and the revert fixes it.

For the second elevation, d79c350 is unrelated, so are a few commits nearby. So it is probably something else. Maybe builder change?

Then I pulled the test timing data for the 1.22 release branch, which doesn't have any of those commits.

It seems the timing also rises since June 24, on 3560cf0. The commit might be related, but the corresponding master branch CL landed on May 15, which did not cause the time rising. As the rising on on the release branch is about the same time as on the master branch, I'm more leaning towards builder configuration change. @mknyszek is there any builder configuration change at the time around June 24 or so?

Lastly, the test has a hard-coded 1 minute timeout. I don't think it makes much sense to say 55 seconds is pass, 65 seconds is fail. So the 1 minute timeout may be a bit arbitrary. We probably want to replace it with t.Deadline.
