11437	TMS failed tiles make CPU load go up indefinitely; remove/readd layer doesn't help	alv	alv	"This started with r8339, didn't exist with r8109). At least one other user has notices this, too.
==== What steps will reproduce the problem?
1. Add imagery layer, pan around until one tile remains black or the lower zoom level tile is never replaced for that tile.
2. Notice the computer fan pick up some speed, because something is doing nothing all the time on one core (here: 25% load on a 4 core machine).
3. Panning to a screen with only correctly loaded tiles visible does not help.
4. (Unconfirmed, but it seems the proportion of missing tiles increases, as the recently added #10902 threads keep waiting for the first unsuccessfull tile(s)?)

When loading a tile is never finished, something consumes one core's worth of CPU constantly. Only minimizing JOSM or hiding the imagery layer stops it, but it resumes if reshown; even if JOSM is not in the foreground, it keeps doing nothing with great effort. Removing imagery layer and re-adding it does _not_ help this.
