Fixed in CVS - warnings will be logged to stderr if no log file was
specified.

Fixed doc in CVS.

Fixed in CVS.

Running admintests correctly is hard - I've never gotten the web distrib
tests to pass. In general these tests are more for the release manager
than for end users.

Probably not.

Basically, Twisted logging starts out with all log.msg() messages being
discarded, and exceptions, errors and in CVS warnings, logged to stderr.
startLogging() will set it so all messages get logged to the specified
file-like object.
