Dear all, are there any plans to move this quite old issue forward?

I stumbled across this issue, because I found that at the moment there is no out of the box solution to use  tempfile.NamedTemporaryFile in Windows in such scenario (which is often used in unit testing):

* in test module:
1) create and open temporary file
2) write data to it
3) pass name of the temporary file to the operational code

* In operational code, being tested
1) open file, using name of the temporary file 
2) read data from this temporary file
