class QueueHandler(logging.Handler):
    """
    This handler sends events to a queue. Typically, it would be used together
    with a multiprocessing Queue to centralise logging to file in one process
    (in a multi-process application), so as to avoid file write contention
    between processes.

Some thoughts about Celery and logging
======================================

LoggerAdapter
-------------

It appears that the use of LoggerAdapter is to get the processName into the
LogRecord (at least, that's what _CompatLoggerAdapter does) but if
LoggerAdapter is defined in logging, _CompatLoggerAdapter won't be used.
