[pulseaudio-discuss] [PATCH] Add support of callbacks for operation cancelation

[Favonia]

Thanks. I'm still interested because we're working on a full Haskell
binding for PulseAudio (in a very, very slow pace, though). I assume
you're talking about an interface similar to
pa_stream_set_state_callback(). If so, it looks more consistent with
the current PulseAudio API. In either way we can deal with it much
more efficiently than the old API.
