OK, seems to work now, but it's still no faster:

SDET 128 (see disclaimer)
Throughput Std. Dev
2.5.70-mm1-ext2 100.0% 0.1%
2.5.70-mm1-ext3 22.7% 2.0%
2.5.70-mm1-noxa 21.4% 4.6%
2.5.70-mm2-ext3 20.5% 2.4%

(last one has both your patches in).

I had the sem tracing one in there too, but got no output. I might have
another look at that later on ...
