Also noted when I saw it. Again, seemed to be more effort than I wanted, though if someone were to say "well, that's what you're stuck with if you use that legacy stuff" I'd be off to do the thing. > I'm very curious what is going on here, and whether it's a logging system > bug.

There is something in my code somewhere that is causing this. I have no idea what it is, yet, but when I put together a minimal web server that uses twisted.reactor.callLater() to periodically start a background task, Twisted is not grabbing stdout or even pushing its own logging to sdtout. I think it might be how I set up the original project in my IDE - for the sample project, I started with a clean directory and clean project file (PyCharm if it matters). So I'm gonna pursue that further. I think that it might be the IDE's environment if you tell it "this is a Flask project". I was seeing weird things from the minimal example as well until I cleared out all the IDE meta files and reinitiated it as a "pure Python" (in PyCharm terms) project. Thanks for your time and thanks for the push that got me moving (hopefully) in the right direction. :) Regards, Jeff
