I hear you and thought of that too. There may be a middle ground which is good enough here:
create the files with a date (and possibly PID) stamp, but rename them to a predetermined fixed name after they're closed cleanly just before program exit.

That leaves around the logs of sessions that crashed, but the less interesting logs can be subject to a cheap rotation scheme without a lot of risk.

I'm curious though, why does my QTemporaryFile trick to auto-remove only empty files not work as expected?
