I don't think it is papering over the issue. We do detect the EPERM and
record it as an environment that is UNSUPPORTED. Which is imho a better
state than still trying to test and then FAILing the testcase.

Note that in the buildbot the test results and out files are put into
the bunsendb so that you can easily see why a particular test was
UNSUPPORTED (or why it FAILED).

We might not like that there are execution environments where some
syscalls return EPERM, but (sadly) they exist and handling and
recording that in the test (instead of simply failing) seems the best
way to handle that.

It also makes sure we have a zero-FAIL testsuite, which is really
useful.

Cheers,

Mark
