Note that neither approach will work for one common use of extracted
files: extension modules and shared libraries on Windows.  Unlike
*nixy operating systems, you can't delete an open file on Windows, and
loaded .DLLs are open files IIUC.  Unless you've got some way to
unload the .pyd or .dll files, you won't be able to do a complete
cleanup in that case.  (This use case is actually why I took the
caching approach rather than the tempfile approach in the first
place.)
