KVA on ppc is limited to 512MB i am told. would you then recommend more like 170MB? this works, though there was a long long pause i thought there was a problem why my build was running though GCC. that's a different issue, though again it was the page daemon cpu spinning for a long time. i wonder if it should sleep for a second if it has looped more than N times in a row without entering the wait section of the loop. for N=1000 maybe? .mrg.
