The easiest way to have an appender flush automatically is setting
its autoflush property:

    log4perl.appender.Logfile.autoflush = 1

What I find puzzling is that both Log::Dispatch::File and Log4perl's native
file appender Log::Log4perl::Appender::File have autoflush *on* by default.
You might want to make sure the log message actually gets through
Log4perl's filtering mechanisms (level, category).
