Wow. That sucks. This is like a standard practice on Linux. A lot of
code uses (Q/K)TemporaryFile to generate a name and then passes that
filename to someplace else. Not a problem so long as the original
handle stays open until the new file is created. If you remove the
temporary file and then create a new file afterwards it leaves a
window open whereby (I believe) certain security attacks can be made.
Everything just gets messy.
Someone correct me if I'm wrong, but I really thought that python uses
this method to create invisible temporary files, even on Windows.
Unfortunately I don't have a Windows box handy, but someone may want
to look into how tempfile.TemporaryFile() works in the windows version
