Hi Dawid, I looked at this and also https://github.com/apache/lucene/issues/7687

If you look at the instances and how sporadic they are, the problem
could be caused by TimeoutSuite using wall-clock time in
com.carrotsearch.randomizedtesting? Especially in virtual machines,
wall-clock time can be extremely inaccurate when you spin them up,
then there's a big correction (via NTP or VM agent).

I have no proof this is what is happening, except to say, I think it
would be better if randomizedtesting used monotonic time (nanoTime)
rather than wall-clock time (currentTimeMillis). It would make it more
robust.
