Would it make sense for dshare, and other d-* plugins, to use a shared 
snd_atomic_write_t in the shared memory segment and associated 
snd_atomic_write_xxx() & snd_atomic_read_xxx() calls?

It's not recommended and not expected to work well always with DMA
buffer.  And above all, these calls were dropped in the recent
alsa-lib.
