In cheesetracker, only one thread writes to the DSP and manages audio
.. the main one is for the GUI. Intercomunication between both is done
via shared memory, unless on destructive operations, where locking is
performed. (lock on the gui, and trylock on the audio thread). This is to
ensure that jack will not kill the app :)
