> Have appender implement the java.io.Flushable interface, or a logback-specific interface if preferred, so that we can call Appender.flush() to manually flush the appender's writer. Not all appenders would have this, only those  that implement Flushable.
> This would be useful in the context where buffered IO is used, but we still want to ensure a flush is made at specific intervals. For instance, in development I create a Spring bean that listens to application events, and force-flushes logback after each http request has been processed by my application, ensuring that I always see all the error logs when something fails.
> I have accomplished by subclassing RollingFileAppender to implement Flushable, quite simply like this:
>     public void flush() throws IOException
>     {
>         writer.flush();
>     }
