I think you understand the module correctly.

I don't know the answer, but it has nothing to do with the logging 
module. The question is, can the same file reliably be opened twice for 
writing in the same module.

Another option: If you configure logging in code, you could create two 
StreamHandlers that log to the same file - open the file yourself and 
pass it to both handlers. If you do this you will have to close the file 
yourself somehow.
