Those SCTP chunks data retransmissions will use bandwidth, that won't be available for audio and video. Note that audio/video may be hardware accelerated and not affected by the js loop at all.

I am speaking about receiving data, not sure how the .send call is involved. And I was referring that without a new API we will be in this situation anyway. Maybe the sctp transmission will not be halted, but the browser will die when having reserved several GBs on intermediary buffers. So yes, I prefer the sctp spontaneous deadlock (Note: I am speaking without an API change).
