Final NonStop test results on 2.21.0-rc2:
t0021 subtest 15 failed - apparently flakey test case
t9001 subtests 33,81,117,118,145 failed - Not new. This is unsurprising as
this never worked. It might be nice to fix, but $DAYJOB.
t9020 subtests 1,2,5,6 failed - Not new. unsurprising as there is no SVN or
perl with SVN module on platform. It might be useful to have a detection to
skip of Perl SVN is not present.

Overall, pass and much better than prior releases.

Cheers,
Randall
