The culprit looks clearly unrelated.

Dashboard:
https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=webkit_layout_tests&tests=global-interface-listing-shared-worker.html

Looks like just being slow?
I'll mark the test as slow.

Status: Fixed (was: Started)
According to the dashboard, the test has been passing (while taking <=64 sec).
Probably it is acceptable to marking the test as SLOW, due to a very large number of postMessage()s with SharedWorker.
Closing as fixed.
