I've taken the machine offline in Jenkins.

Start with the failing test/pummel/test-fs-watch-non-recursive.js at the reported fs.watch call, then review the linked Jenkins run and the test-ibm-aix72-ppc64_be-2 machine state. Determine why the AIX worker reaches its file-watcher limit; done means the test no longer fails for this ENOSPC condition and the worker can return to service.
