 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.
