	could anyone with lmbench do lat_rpc with the old code?

	the numbers i've posted (hoge.c) could be misleading, as (1) it only
	measures the algorithm itself, not the impact to RPC code as a whole,
	(2) it runs on userland so kernel-userland overhead like gettimeofday()
	call which makes it inaccurate.
