I tried it, but it made no difference on my Thinkpad X200, which still
fails the same way as before with 10.1.38:

  Failing test(s): tokudb_bugs.mdev4533

Anyway, based on Giovanni's observations,

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35521#32

I'm now inclined to agree that these are likely to be flaky tests, so I
withdraw my objections to disabling them, in this specific case.

Having said that, I disagree with Giovanni's dismissal of my concerns in
general, here:

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35521#29

I will respond to that dismissal in a later message.

     Thanks,
       Mark
