This test is quite flaky on MIPS post-commit bots. See https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/5731/steps/jscore-test/logs/stdio and https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/5716/steps/jscore-test/logs/stdio to check failed builds. There's no such kind of failure on EWS and we also couldn't reproduce it on local device.
