No idea yet whats happening here, I get 100% success rate even
when running this thing 1000 times in a loop.

I sent a patch to no longer treat '127 of 128' et al
as a hard error, i.e. the test should then either SKIP or pass.

And I added a bit more information, maybe the next test run
will tell more.
