The critical point is that you cannot always do that. Retaking my
example of mkstemp: I have a C library which has a fdopen-like
function (built with one C runtime, not the same as python), there is
no way that I know of to use this API with a file descriptor obtained
from tempfile.mkstemp function. The only solution is to build my own C
extension with C mkstemp, built with the same runtime as my library,
and make that available to python.
