Code Review Request: 7184287: (prefs) BackingStoreException when calling flush on root node[macosx]

[Kurchi Subhra Hazra]

Hi, 

While flushing user preferences, a BackingStoreException is not expected, since 
the current user should be able to write such preferences to the 
persistent storage (unlike system preferences, where current user needs 
to have admin rights). This fix aims at allowing a user preference node 
to flush any changes to the persistent storage on Mac OS X.
