The "main" function is called more than once when fetching for lyrics.

The method "PluginController - (NSString *) lyricsForCurrentSong:(BOOL)checkOnline" is called twice when the plugin updates the lyrics view. Combined with various other script calls that should be cached, this causes major slowdowns.It also seems to be the root cause of iTunes 10.0.1 incompatibility and the thread locks that have been reported.
