Yes. This is possible, (in fact, the refbufs have to be explicitly tagged as 
being droppable or not, we can't discover it after the fact), but it's added 
complexity for a feature which is of very dubious benefit anyway. The 
processing model of icecast assumes a continuous connection - if they can't 
keep up, the client will probably drop anyway. It's much better to just let 
the client auto-reconnect (which most of them do).
