Request: flushAll method on loggers for writer appenders

Hello,
Would it be possible to add a flushAll() method on the logger & appender 
interfaces that will trigger an immediate flush of the ostreams of
the WriterAppender derived classes?

Reason we need it, is we have a very demanding application which need to use 
the BufferedIO/ImmediateFlush pair for gaining performance,
but at some stage (when getting a specific signal) we would also like to be 
able to flush whatever is currently in the buffers.

The only way I know of doing it non-intrusively at present is:
1. Iterating on all the appenders on the logger's hierarchy.
2. Setting the BufferedIO/ImmediateFlush to false/true respectively.
3. Sending a "Flushing All"  bogus message.
4. Reverting flags to what they were before by re-iterating on appenders.

Which, needless to say, is an extremely ugly solution...

Implementing it as part of log4cxx (and/or log4j?!) seems much simpler and 
cleaner.

Thanks,
Please let me know what you think,
Barak
