Yes - I saw that - thanks. This suggests that as I have used
closed_fds=False, then the child process will inherit the handles under
Windows, which it doesn't seem to. This documentation looks wrong to me.
I know Windows has no fork - that's why I used subprocess. This MSDN page
suggests you you need to do something with SetHandleInformation to get them
to be inherited. Doesn't subprocess do that?
