The test URLRequestQuicPerfTest.TestGetRequest is flaky. Occasionally, a ZX_ERR_CANCELED error is raised, which then leads into a fatal error stating that the current task needs to be run from a SingleThreadTaskRunner. The failure can be replicated with the command 'out/fuchsia/bin/run_net_perftests -d --gtest_filter=URLRequestQuicPerfTest.TestGetRequest --gtest_repeat=1000 --single-process-test'
