Around 25% of test runs fail with the assert in the last line `lldbutil.wait_for_file_on_target(self, exit_file_path)`
```
AssertionError: File C:\buildbot\as-builder-10\lldb-x86-64\build\lldb-test-build.noindex\commands\process\detach-resumes\TestDetachResumes.test_detach_resumes\exit_file_1750332982 not found even after 6 attempts.
```
Note the file `exit_file_*` is really missing after this test. This issue is easily reproducible locally running

```
It seems something is really wrong with the detaching on Windows x86_64 in case of multithreading.
