In random order: Thanks to Chris Eby for his work on pithos, to an anonymous coward for sending me his Android client, to Alex Howard for sending me the webOS client, to ZigZagJoe for providing a temporary fix and thanks to everyone who sent Pandora a message. Although there are a few rough edges here and there this fixes #236.
Strict pthread implementations (like OpenBSD’s rthreads with PTHREAD_MUTEX_TYPE_STRICT_NP set) don’t allow unlocking a mutex that is not locked, resulting in abort() being called. Always aquiring the lock before unlocking it while skipping to the next song fixes this. Thanks to David Coppa.
