On the DS20 I have here, Peter's fix to basically enable the buffer cache
gave me about a 38% performance increase for a buildworld -j 2 on current:

Before:
--------------------------------------
build started at 15:11:08 on 08/28/02
build finished at 18:43:05 on 08/28/02
--------------------------------------
Which is a total time of 3:31:57

After:
--------------------------------------
build started at 22:41:31 on 09/03/02
build finished at 00:51:46 on 09/04/02
--------------------------------------
Which is a total time of 2:10:15

If this bug exists in 4.x we should really fix it there as well.
