May I suggest that we remove aserver and the shm plugin instead of 
applying the patch? Three days ago I tried to use it for testing my fix 
to the share plugin, but failed. In other words: if even speaker-test 
cannot be made to work on it without crashing and/or hanging or valgrind 
errors, then I'd rather be aggressive here.

And next time please CC: Takashi Iwai on all alsa-lib patches :)
