True enough. IIRC, emphatic deals with tracks changes by watching the notify thread, and if playback was halted during that moment when emphatic was loading the file, I doubt that emphatic would know - I think that it only watches the notify thread for timing purposes, and wouldn't catch the halt. That raises the question of how long emphatic would take to complete the read, and how long the sync code in the player is going to wait before attempting the umount. I'm hazarding a guess that the player is only going to wait until any current cache load terminates or completes, leading to a potential race hazard if a sync is initiated just as the track is changing. (Obscure and infrequent to be sure).

Maybe I'm wrong - maybe emphatic completes the read fast enough for this to never be an issue. How long would it have?
