This patch introduces "BATCH" mode.
In this mode, a client can feed multiple commands to rrdcached without
waiting for acknowledgement. This permits multiple commands to be sent
for each read()/write(). This can dramatically increase the command
throughput by increasing the amount of work done per system call.
It enables over 100k updates/second with no CPU
utilization due to the reduced system calls.
