It's not related to this PR, the test is just extremely racy (see #346 (comment)). /cc @dtardon

It seems the test for #346 is not reliable enough after all. I really don't want to backport later improvements to it, as they depend on general improvements to TEST-35-LOGIN, so we probably should disable it.

Or we could just pick up the necessary minimum that's needed to run the test from the current upstream version instead of backporting separate commits (which didn't even occur to me when I was doing the backport, because I'm too used to the latter). That shouldn't be that much work...
