Research direction
Investigate the timeout in TestCrashDumpsAllThreads by examining the captured log and reproducing the failure. Look for goroutine leaks or blocking operations in the runtime/crash test.go file. Check recent commits in the runtime package for changes that may have introduced the timeout. The issue is tracked by watchflakes and may require coordination with maintainers.
