If you're being asked this frequently, I'd recommend adding some notes to
the documentation, recommending using poll() and not SND_PCM_ASYNC, and
offering a brief explanation like this one.

James, I don't know if this is of any help, but you could always have a
peek at the PortAudio (www.portaudio.com) code (pa_linux_alsa.c). We don't
use snd_pcm_async_handler though, but implement async and blocking IO
ourselves.
