random tests failing on s390x

That's my conclusion.

We also have a s390x instance in our own "vtest":

	https://vinyl-cache.org/vtest/

and it shows similar random lossage, even though we run that
platform with VTEST_DURATION=180

That said, some of our test-cases are more sensitive to timing than
others, and we try to improve that where we can, and I recoginize
the cases you mention as being on my personal "trouble-list".

We have discussed if some tests should be "advisory", in the sense
that a failure is just a "warning" not an "error", but that feels
too much like giving up :-)

I would disable tests on s390x.

Never attribute to malice what can adequately be explained by incompetence.
