TestWebKitAPI.WebKitLegacy.CrossPartitionFileSchemeAccess seems flaky on macOS. In https://ews-build.webkit.org/#/builders/3/builds/16434, the test TimedOut in run-api-tests step. However, in the immediately next retry step (re-run-api-tests), it passed.

Looking at: https://results.webkit.org/?suite=api-tests&test=TestWTF.FileSystemTest.MappingExistingFile The test timed out on trunk bots between r254548 and r254560 (which rolled out r254548), and one time on 12/29/2019 @r253935.

This test has started timing out on almost every Mojave API test run. It had been frequently timing out on debug only, but now it is timing out on release, too.

Comment on attachment 419147 [details] Patch Nothing goes to stderr. A description of what it has done goes to stdout.

r272765 should make EWS happy for another year. I still have no idea why it is timing out only on EWS bots.
