I would say answering this question is your task, since you have access
to that buildbot.

This is not cosmetic, the thread might be keeping all kinds of resources
alive, it might also break other tests which expect there to be a single
running Python thread (if e.g. signals are being tested). We don't want
a failing test to trigger a potential cascade of subsequent failures.

The issue is not to satisfy me, it's to satify the buildbots. If you say
that 5 minutes is necessary to reliably resolve "localhost", then surely
there's a configuration problem?

If you say that replacing "localhost" with "127.0.0.1" would fix the
issue, then perhaps we should do that, but we must check that it doesn't
break any other tests (for example IPv6 tests).
