[flake] lldb-api :: tools/lldb-server/TestGdbRemote_qThreadStopInfo.py is flakey on Windows x86_64 #9101

@tkremenek can you please help me by adding the flakey-test label to this issue, as well as the others listed in this query? I don't have write-access to issue labels, and am working on standing up LLDB tests on our Windows x86_64 builds.

Interesting questioning what to do about tagging. Is this a test that comes from upstream LLVM?

Yes, lldb-server is a debugserver implementation used on all non-Darwin platforms.

@kendalharland ... which is why we probably should make that change on llvm.org and then cherry-pick it here.

@adrian-prantl this test is not flaky on Windows upstream from what I observe. This flake only happens for me in swiftlang's llvm-project fork,, so I believe the bug belongs in this project. For context on this issue and others: I'm currently working on getting the LLDB tests to run on the Windows x86_64 CI builds of the swift toolchain, driven by swiftlang/swift/utils/build.ps1. See this issue. As a baseline I'm using the results from a local llvm/llvm-project build of the LLDB tests.
