- I did think of that too - but the syncing may fail(temporarily) if the 
prefs object could not retrieve the lock to the
associated prefs file. We could stop syncing attempts if the sync fails 
say n number of times - but I do not think
that is a good solution.
  We may however be able to stop the syncing attempts if we are 
guaranteed by some error code that any future
writing attempts will fail. I'll check on that.

Preferences use sun.util.logging.PlatformLogger.java which is enabled by default, and has a default level of INFO. Changing the logging in this file to FINE prevents the user from seeing information that he/she is not interested in.
