> There's a bug in THttpTransport that causes it to hang when sent a large,
> chunked request.
> The issue is that in each call to THttpTransport::read(), it always starts by
> calling refill() which reads more data off the socket, but for chunked
> requests each call to read() only processes a single chunk.
> So, if more than one chunk is read off the socket at a time, you can end up
> with more chunks still needing to be processed but no more data to read off
> the socket, and the next call to THttpTransport::read() will hang when it
> calls refill().
