After open_osfhandle(), the handle is owned by the file object, and should
not be closed when the PyHANDLE object is deallocated.
Did you try to use the Detach() method? Something like
   fd = open_osfhandle(h.Detach(), os.O_RDONLY)
Documentation says: "You would call this function when you need the
underlying win32 handle to exist beyond the lifetime of the handle object"
which seems adequate here.
