Layout-tests seems to be hanging (and getting killed by buildbot after 20 minutes) on iOS EWS. e.g.: https://ews-build.webkit.org/#/builders/24/builds/24138/steps/10/logs/stdio 13:58:29.862 4724 worker/9 starting 13:58:29.873 4724 "xcrun --sdk iphonesimulator --show-sdk-version" took 0.01s command timed out: 1200 seconds without output running ['python', 'Tools/Scripts/run-webkit-tests', '--no-build', '--no-show-results', '--no-new-test-results', '--clobber-old-results', '--release', '--ios-simulator', '--results-directory', 'layout-test-results', '--debug-rwt-logging', '--exit-after-n-failures', '30', '--skip-failing-tests'], attempting to kill process killed by signal 9 program finished with exit code -1 Seems to be happening consistently: https://ews-build.webkit.org/#/builders/24/builds/24140 https://ews-build.webkit.org/#/builders/24/builds/24139 https://ews-build.webkit.org/#/builders/24/builds/24138
<rdar://problem/67584717>
It seems to have started in https://ews-build.webkit.org/#/builders/24/builds/24053 (started around Aug 20 8:45am, which was built with r265943) previously, https://ews-build.webkit.org/#/builders/24/builds/24051 passed successfully. Seems to be due to https://trac.webkit.org/r265942 which made changes to Timeout and was landed just before the first noticeable failure (Aug 20, 7:33 am).
Something super weird is going on, going to upload a partial revert of https://trac.webkit.org/r265942 (one that doesn't revert the parts that would be conflicts)
