I stored a snapshot here. Can't shorten the timeline I think, but 
resetting telemetry caused only the last "long event" of 8s having call 
stacks I think.

I don't understand why the events tab does not have call stacks recorded.

It seemed that whenever I did not use JOSM for a few minutes because I 
scrolled around in the profiler or source and then go back to JOSM and 
zoom I got a wait. One time over 22 seconds.

Can someone more familiar with the profiler confirm that the AWT loop is 
not blocked but simply busy for that long?

Is it filling tasks to JCSCachedTileLoder.submit()?
I don't know how to limit the CPU analysis to that timeframe to see 
where the cycles go.
