Yes, see attached worker.html and worker.js. worker.js periodically sends a message to its worker object so the worker context is not collected. However the worker object is not GC protected and I see only part of the messages printed in the page. I can reliably reproduce it on Chromium Linux after the page refresh: messages from worker #0 will never be printed.
