Running this version for 2 days now on heavily used build machine.
No problems to report.  Here are some numbers for kernel build.
Machine is SMP, 2 Xeon P4, Intel chipset, single IDE HD, with
hyperthreading enabled.

2.5.67-bk4 (i think bk4):

       make -j1   make -j4
       --------   --------
real   5m03.889   2m37.253
user   4m27.550   4m41.037
sys    0m27.727   0m29.651

2.5.70-mm1:

       make -j1   make -j4
       --------   --------
real   4m52.212   2m41.565
user   4m27.447   4m40.462
sys    0m29.079   0m31.184

This test does not show any significant difference.  On the other hand,
even with -j4 the disk activity is light.  If you have a better test
that you would like me to run, point me to it, and I'll do it.
