    <thetext>We have started seeing frequent assertion failures in InspectorTimelineAgent::didCompleteCurrentRecord a couple days ago. Not a lot of tests crash, but overall, this nearly blocks debug EWS.

E.g.:
http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#tests=imported%2Fblink%2Fanimations%2Fbase-render-style-body-crash.html
http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&amp;tests=imported%2Fblink%2Fcompositing%2Flayer-creation%2Fiframe-clip-removed.html
