There must be more to the problem than just an open file. Please undo the change that triggered the addition of the test, and see whether you can reproduce the original problem with an arbitrary open file (I could trigger the problem with pagefile.sys at the time).

I think the point is that the problem should be solved (stat of open file) for any arbitrary open file including pagefile.sys.

After booting into Win98, I can see that I have a pagefile.sys indeed in my C drive which WinXP hides from view. While in Win98 and with the file not in use, the test passes on Win98 when looking for pagefile.sys in C drive (no complaint about file not found or access denied, even though I know that the file is not open). And the test passes for the running python.exe that is processing the test.

After some googling it seems to me that this could likely be a User Rights Assignment issue of a systems file not an open file stat one, hence the Access denied error message (winerror 5) that I got in WinXP, as opposed to the File not found windows error (winerror 2) which one might expect if the pagefile.sys did not exist.

And therefore if the point of the test is just to test stating an open file then the temporary file approach makes sense. If modifying a systems file with or without User Rights Assignment is a requirement then we may need a new test altogether.
