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?
