Oh, yuck, you're right.  In that case the only way to make this test
reliably test what it's supposed to, will be to introduce a .fdopen()
extension method so that we can provide exactly the right flags to the
open() system call.  Which I suspect there's user demand for, anyway,
but it's a 3.5-only thing.
