Example A: screenshot of htop showing two baloo_file processes
The baloo_file process for a user continues to run after the user leaves the destkop environment.
Subsequent reuse of the DE by the same user results in a concurrent (higher numbered) baloo_file process, under which baloo_file_extractor processes sometimes run.
Whilst I have never observed a baloo_file_extractor running under the lower numbered baloo_file process in this situation, I assume that it's unnecessary to have two baloo_file processes.
