test_profiling.test_sampling_profiler: test_run_failed_script_live() hangs on multiple buildbots #150387
Description
test_run_failed_script_live() hangs on multiple buildbots:
- AMD64 Arch Linux Asan 3.x: https://buildbot.python.org/#/builders/582/builds/7159
- AMD64 Arch Linux TraceRefs 3.x: https://buildbot.python.org/#/builders/484/builds/7167
Example:
test_run_failed_script_live (test.test_profiling.test_sampling_profiler.test_live_collector_ui.TestLiveModeErrors.test_run_failed_script_live)
Test that running a failing script exits with clean error. ... Timeout (0:20:00)!
