Since this is in a pretty-new process, it would have to be global FD
exhaustion, that is ENFILE not EMFILE.  (Assuming macOS even has
that concept; its BSD roots sure do, but who knows what Apple's
done to it over the years.)  You'd likely have seen more side-effects
of such a condition.

I was wondering more about permissions checks gone wrong, comparable
to the antivirus-induced misbehaviors we hear about on Windows.
Not that that's a comforting answer.
