 After many additional test runs, I'm still confused as to what is
 going on.  My own testbed agress with the TNF one that the problem
 started with ad's commits of Jan 15:
 
   http://releng.netbsd.org/b5reports/pmax/commits-2020.01.html#2020.01.15.17.55.43
   http://www.gson.org/netbsd/bugs/build/pmax/commits-2020.01.html#2020.01.15.17.55.43
 
 On both testbeds, the tests then consistently failed to complete until
 around Feb 2, but since then, the behavior has been random and
 different between the testbeds:
 
   http://releng.netbsd.org/b5reports/pmax/commits-2020.02.html#2020.02.02.06.41.27
   http://www.gson.org/netbsd/bugs/build/pmax/commits-2020.02.html#2020.02.02.03.41.12
 
 The pmax tests have been printing the message "warning: LOW reference"
 since ~forever, but what has changed is that they now end up printing
 them in a tight loop (or not, as the case may be).
 
 The hpcmips tests have failed to complete in every run since Jan 15,
 but it's hard to tell if the problem started with the same commit as
 the pmax one because they were already randomly failing to complete
 before that:
 
   http://releng.netbsd.org/b5reports/hpcmips/commits-2020.01.html#2020.01.15.15.30.46
