Thanks for the query. I haven't knowingly added any strange jobs;  there 
are just software notification tools etc.  journalctl grepping 
"Successfully made thread"  does find mythfrontend, firefox, pipewire, 
pipewire-pulse, wireplumber,  with increasing thread ident numbers...

There are many fewer "Successfully demoted thread" events, the latest on 
7 March.

and there was a pipewire update today.
