It's hard to tell because the failures have been so sporadic.  On
the TNF i386 testbed, the failures so far were testing sources
from the following dates:

  2019.06.21.14.58.32
  2019.06.25.04.25.11
  2019.06.25.05.04.35
  2019.06.25.07.14.45
  2019.06.25.10.30.29
  2019.06.25.16.58.02
  2019.07.03.23.10.43
  2019.07.04.09.02.24
  2019.07.09.02.50.24
  2019.07.14.11.27.33
  2019.08.01.17.50.16
  2019.09.23.18.43.59
  2020.03.15.07.56.19
  2020.03.15.12.12.42
  2020.03.23.15.32.56

That's a period of almost six months with no failures before
the latest set of failures in March.  Unless someone can come up
with a reliable way of reproducing the bug, I figure we have to
wait at least a year before we can be be reasonably sure it has
been fixed.
