I could get that with str(sys.exc_info()[1]), though. If something
raises a WindowsError, str(sys.exc_info()[1]) contains something like:
[Error 183] Cannot create a file when that file already exists:
<file/directory>

sys.exc_info() is how I get the error code from inside an except clause
in the first place. Or is there something I'm missing here?
