Changed default value of sendfile_max_chunk to 2m.
The "sendfile_max_chunk" directive is important to prevent worker
monopolization by fast connections. The 2m value implies maximum 200ms
delay with 100 Mbps links, 20ms delay with 1 Gbps links, and 2ms on
10 Gbps links. It also seems to be a good value for disks.
