I am able to reproduce this failure locally using command:
run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build --child-processes 50 http/tests/cache/disk-cache/disk-cache-remove-several-pending-writes.html

This is not Mac WK2 specific. GTK, WPE and WinCairo are also flaky.
