Until now: no. But, during Peak hours, the load is MUCH higher (upto
1024 active httpd's).  When spread uses 60% of the cpu handling 300
httpds, this might become a bottleneck (select is O(N) on linux afaik). 

Besides, i would like to use the cpu for other tasks, more servlet
engines for example (these are currently running on a separate cluster).
