Modify the SPDY stream to be buffered.
Discovered that passing small chunks of data to the renderer can cause the
renderer to get backlogged. With SPDY, data chunks are always framed into
smallish chunks (say ~4KB). So where HTTP would only send a couple of large
chunks to the renderer to satisfy a resource load, SPDY may send many, and
this was surprisingly slow.
