Jun 2th mm patch on top of ac7

[Ed Tomlinson <tomlins@cam.org>]

Hi,

Subjective performace of the system is much nicer with the Rik's june 2th 
patch applied on test1-ac7.  I am now able to have a news cache, a java 
server, browse and play mp3(s) without the jerkness of the May 31th patch.

Some vmstat numbers follow:

   procs                      memory    swap          io     system         cpu
 r  b  w   swpd   free   buff  cache  si  so    bi    bo   in    cs  us  sy  id

 1  0  0  18680   3300   6072  40308  24   0    16     6  207   884   8   2  90
 0  0  0  18680   4800   6096  38168   0   0     5     1  189  1021  10   2  88
 4  0  0  18680   5332   6096  38224   0   0     0     0  176   853   9   3  87

The box is not heavily loaded.  One difference from earlier vm(s).  The ammout of
memory allocated to buff is less now (was 10000-15000).

I am not subscribed here so please repond to my personal address.  

TIA,
