For synchronous request, if get_avail_data returns 0, we call blocking 
refill_read_buffer which may start the new chunk. There is no reason for 
get_avail_data to block.

Also note that that's not the interesting thing to test in regards to 
chunks handling. The tricky part is async request handling.
