What is this actually testing? It seems to just add the data to the
SeekableBuffer.  Seems you could just replace this with an AudioFifo.

[henrika (OOO until Aug 14), 2014/06/17 11:39:44]

The buffer is read out in the OnMoreData, hence you will hear the audio in
loopback. I will add a TODO to replace with AudioFifo. Would like to land this
one first.

PS, this file is not even included in media.gyp.

       // An attempt to write outside the buffer limits has been made.
