Well it seems that with current PA it would be quite difficult to do because
the shm-size is configured on daemon side. So when the PA context is created by
the client, the daemon will create a new pa_mempool based on the shm_size
declared in daemon.conf. I found no public API to update that option.

Sebastian proposed a better long term solution which would be to make all
pulsesinks (in the same process) share a common context.
