Konstantin,
the EditLogI/OStream in the .19 didn't allow me to modify the logSync() method which is something
crucial for the integration with BookKeeper. Will the patch you'll post fix the issue? What
I did is basically to implement the EditLog as an abstract class and override what I needed.
In this way also the code in FSEditLog was much cleaner. What do you think? 

dhruba, yes, I'm referring to FSImage.java, btw: Konstantin, will your patch support multiple
logging system at a time?
