All Python in Kodi shares one interpreter lock. A plugin run the user started (a dialog, a listing, playing a title) therefore competes with whatever the service does in the background at that moment: preparing rows, loading sections off-screen, refreshing caches. Measured on a slow machine, opening a dialog took 0.8 s alone and 2.7 s while rows were being prepared. `mark()` is called at the very start of every plugin run that is not a Home row, and for every request the skin sends to the service. The background loops call `give_way()` between two pieces of work and wait until HOLD seconds have passed since the last mark. Nothing is cancelled, only delayed, and never longer than `limit`. Work that is not a loop of the service (the Pro tebe rebuild, the refresh of a show's metadata) calls `breathe()` between its steps. That does something only in a thread that said `background_thread()` first, so the same code run by the user (a manual rebuild, a plugin call) never waits for itself. Kept light: main.py imports this module first thing.
