    <thetext>Test has been showing up on dashboard with iOS Simulator Release and Debug.

Dashboard:

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&amp;tests=http%2Ftests%2Fcache%2Fdisk-cache%2Fmemory-cache-revalidation-updates-disk-cache.html

Reproducible with:

run-webkit-tests http/tests/cache/disk-cache/memory-cache-revalidation-updates-disk-cache.html --iterations 500 --child-process 1 --ios-simulator --no-retry --exit-after-n-failures=10

Will fail approximately 1 in 500 iterations. 

Unable to duplicate locally with Debug builds.
