performance of new code

[Katsuhiro Kondou]

I think my patch works fine without any problem so far.
There may be some problem which I didn't find yet, however.
I'll commit it soon.

For those who are interested in, here is performance
comparison between current and patched one.  Testing box
is Solaris2.6 on Netra t1(440Mhz/1GBmem/5*18GB built in
two D130s for cycbuff), and get fed fullfeed(~3MBytes/sec,
~20art/sec).
