setTimeout on the main thread is throttled and timers execute at 1Hz, but the main thread is woken up much more frequently by "message" DOM events, and these seem to be triggered by timers in the DOM worker.

The process priority is "background".

Olli, is it easy to check what the code does and see if throttling of worker timers is just not implemented, or would it be useful to write a reduced test case?

This is now very much known and we do want to do this, or at least I do. It is not implemented, but shouldn't be too hard.
