Summary: Windows service with logging to FILES module 

Initial Comment:

Dears, 

I'm sorry to reopen this bug, but the former was closed abruptly... 
The last paragraph is about the log-to-files-that-fails part.

When I try to use the logging module in a script that is called by a
general script intended to create a windows service that runs the script in
a separated thread, I get an IOError: Bad file descriptor

For exemple, I have a script that polls a value and logs it every second.
It runs flawlessly alone and in debug mode in a service. But once it is
started normally. the log process is successfull several times (8 for
exemple, and always 8) and the next time, the IOError is raised.

I ave tried with several handlers: RotatingFileHandler, FileHandler, and
even StreamHandler, with different polling times, different numberd of
successive writes and some other parameters.

Message:
I closed the bug after indicating the problem.  Note that stdio buffering
is what causes the problem to fail after what appears to be 8 log calls
(but in reality, it fails after a fixed number of bytes are written). 
Unless you can show this is a problem with pywin32's service support, I'll
be forced to close this bug eventually too...
