  # Requirements:
  # - Netcat with Unix socket support (e.g. the netcat-openbsd package on Debian/Ubuntu; not netcat-traditional; you can install both in parallel)
  # - objgraph Python package. `pip3 install --user objgraph` (if you use venvs: in the venv that the AB process uses!)
  
  # Usage:
  # 1. "Pause" the affected job by increasing the delay to a large value (e.g. 3 minutes).
  # 2. Wait until it's idle, i.e. not retrieving data anymore. (That's a bit tricky to verify. You could check the end of the log file or the open ArchiveBot/pipelines/tmp-* files of that process.
  # 3. Figure out the PID of the process: `pgrep -f $jobid`
  # 4. Run the script: `nc -U /tmp/manhole-$pid <cookiejar-empty-hack.py`
  # 5. Wait for it to finish. Do not press ^C or similar.
  # 6. "Unpause" the job by restoring the previous delay setting.
