I use replace.py to collect candidates for working without interacting Wikipedia (with -xml -save); this saves titles for later investigation.
Sometimes this task is done in two or more separate Windows command windows to save time. 2 years ago I could do this with no problem.

Now the second task floods my screen with such messages:
`Traceback (most recent call last):

File "C:\Python27\lib\logging\handlers.py", line 77, in emit
  self.doRollover()
File "C:\Python27\lib\logging\handlers.py", line 350, in doRollover
  os.rename(self.baseFilename, dfn)

`WindowsError: [Error 32] A folyamat nem fÚr hozzß a fßjlhoz, mert azt egy mßsik folyamat hasznßlja
Logged from file wikipedia.py, line 10134``
The Hungarian message means "the process cannot use the file because it is used by another process".
Wikipedia.py, line 10134 is: log.log(_level, text, extra=context, **kwargs) from def logoutput.
