Looking at the AIX runs I've seen a few failures of: parallel/test-cluster-dgram-1

I wonder if its related to this change ?

If the failures are new, entirely possible. Have a stack trace?

We've started to see frequent failures in
test/parallel/test-cluster-dgram-1.js on AIX since the refactoring
in nodejs#8261.  Revert changes
until we have time to investigate properly.
