Description Matt Lewis 2017-07-07 10:34:57 PDT

fast/workers/dedicated-worker-lifecycle.html is a flaky timeout
It is timing out on all platforms according to the flakiness dashboard.
https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fworkers%2Fdedicated-worker-lifecycle.html

The test will timeout with times ranging from 80-220 seconds. Usually it runs under 25 seconds on a pass.
The first timeout occured on this build: https://build.webkit.org/builders/Apple%20Sierra%20Release%20WK2%20(Tests)/builds/2796

https://build.webkit.org/builders/Apple%20Sierra%20Debug%20WK2%20(Tests)/builds/1933
https://build.webkit.org/results/Apple%20Sierra%20Debug%20WK2%20(Tests)/r219255%20(1933)/results.html

I was able to reproduce the timeout locally and narrowed down the timeout starting between r219238-r219239
