The version is the issue - that's an outdated beta version ;) Some versions
had unix sockets flagged as sources that could lightly be delayed, resulting
in what you see. That was made optional in later builds (and I guess nobody
has turned it on since then ;)).

Cure: upgrade to the current (3.22.1) v3-stable.
