not sure what you mean by that? I can build it fine with mingw-w64-g++ and it runs.

this is not true. callback could still be called after MFCancelWorkItem returns success, the [documentation](https://learn.microsoft.com/en-us/windows/win32/api/mfapi/nf-mfapi-mfcancelw...) says as much.

and the thing is, more than this "hit race" case, our current rtworkq implementation triggers a assert in threadpool that says exactly what i predicted (callback is running when you try to close it). and that's exactly the race I am trying to avoid here.

what more proof do you want?
