SUMMARY
Spider (and other games) are writing to the `~/.xsession-errors` file. Spider looks to be the worst offender, but others are writing out also. This file can grow to be very large, and is not under any kind of automatic log rotation policy. I don't know why kpat needs to write so tersely to log files, and if it does need to write so tersely to log files why it uses `~/.xsession-errors`, instead of a more sensible `/var/log/kpat/...` file.


STEPS TO REPRODUCE
1. Open new game of spider
2. Run `tail -f ~/.xsession-errors` in a terminal side-by-side
3. Make any legal move in spider 
4. I believe this prompts the solver to start 'looking'.
5. The solver is just outputting all data to the `~/.xsession-errors` file for an unknown reason.


OBSERVED RESULT
Given enough time, 10's or 100's of GBs of data will accumulate in the `~/.xsession-errors` file and fill the disk.


EXPECTED RESULT
No accumulated disk space waste.
