If you use the same appender in different processes or threads, and the 
appender doesn't take any precautions to separate the messages, they'll 
end up randomly interleaved.

To avoid this, you could

* write a new file appender that obtains a mutex lock before it writes 
(but that's going to be slow)
* use different appenders for different processes
