How to create a temporary file that can be read by a subprocess?

[Piotr Dobrogost]

I've just read this interesting question titled "How to create a temporary file that can be read by a subprocess?" (http://stackoverflow.com/q/15169101/95735). Provided there is a method to make _named_ temporary file being readable by other processes on Windows, the CPython implementation should do just this, no? Right now it doesn't. What do you think?
