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 ...
