I haven't looked into all the various places the tests write temp files to, but if we could localise everything to a common root directory, i.e. %TEMP%\python-regrtest, we could then attempt to blow this away at the start of regrtest.py before any tests run, and refuse to run if this fails.  This would be in combination with the unlinking/renaming approach discussed.  This approach seems like it would cover all bases a bit more effectively.
