p.s. - changed the title: way back when I first started on this I was mainly concerned that the _netstat_getnode() routine was broken for AIX. During the research and follow-up discussions it has become clear that it is more than just an AIX issue. There are multiple aspects that need attention.

Footnote: For most platforms, most of the data accessed via Lib/uuid is actually retrieved via Modules/_uuid. The majority of issues with Lib/uuid occur during testing: ./python -m test test_uuid

At least two PR (8672 - fix bug for AIX), (12777 - make "_getters" lists platform specific when possible). FYI: the first PR (5183) was when I was trying to patch multiple issues.
