(Sorry, I didn't follow the whole thread, and I'm not sure that it's
best place for my answer.)

A quick reminder: this pattern raises a ResourceWarning to remind you
that the state of the file is unknown. Flush to disk? Maybe. Maybe
not.

It's a good practice to run Python with -Wd to see this
DeprecationWarning and ResourceWarning. Use -Werror to ensure that you
handle correctly *all* warnings ;-)
