I know @martinvonz made some other related changes prior to that commit that had similar test fallout on Windows, but it isn't obvious to me why the referenced commit would change the order of when the background thread spins up.

I'm thinking that that commit pushed the number of files to close above some threshold that made it get printed. In that case, it was probably some of my earlier commits that made it no longer get printed and we just didn't notice since `(?)` means optional (no error if it doesn't get printed).

I'm not too worried about why it popped up- it just seemed odd that it didn't with the earlier followup patch I added to fix similar conditionalizing of this exact text elsewhere, and the commit where it started failing looked innocuous.
  
  Yeah, I'm not worried about it either. Thanks for checking. (I wasn't holding off queuing this one because of that, I was/am just busy with other stuff.)
