The problems here are due to concurrency, by the time we fetch the history details, looks like a transaction is still open and we read from an outdated db snapshot.
We could try with some promiseAsyncUpdates() calls...
the failure rates here have been steady for the last 3 weeks, it looks like linux64-asan and linux64-ccov (which is a debug build, but instrumented for collecting code coverage).

Given that we are seeing these on "artificial" configurations- should we skip this for those configurations, or plan on making the test more robust?

::mak, I see you had some suggestions about 4 weeks ago in Comment 1, is this something that could be done in the next week or two?

keep in mind bug 1384130 has many failures in the same test.
I can have a look in the next days.
