Now that FileStream can be used to wrap arbitrary file handles, it is possible that it ends up wrapping a pipe.

In our application we open files in Python code, pass the file handle/descriptor to C++ code, and then use
FileStreamto access the file from C++. It's also possible for Python to pass a duplicate of the stdin handle to C++, so we need to handle theERROR_BROKEN_PIPEspecial case.
