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.

Disabled the test for Mojave in r262851.
Now that EWS bots have moved to Catalina, this test is now very flaky on EWS. e.g.: https://ews-build.webkit.org/#/builders/3/builds/40455 https://ews-build.webkit.org/#/builders/3/builds/40454 https://ews-build.webkit.org/#/builders/3/builds/40452 https://ews-build.webkit.org/#/builders/3/builds/40434 https://ews-build.webkit.org/#/builders/3/builds/40274

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

This test is still flaky and slowing down EWS api-mac queue. e.g.: https://ews-build.webkit.org/#/builders/3/builds/41159 https://ews-build.webkit.org/#/builders/3/builds/41154 https://ews-build.webkit.org/#/builders/3/builds/41145 https://ews-build.webkit.org/#/builders/3/builds/41136
r272765 should make EWS happy for another year. I still have no idea why it is timing out only on EWS bots.
