CPU usage still at 99% on last revision

[GoogleCodeExporter]

Hi

tested today the last revision but it seems the problem is not solved :

#slowhttptest -c 6000 -X -r 200 -w 512 -y 1024 -n 5 -z 32 -k 8 -u 
http://testurl -p 10 -l 6000

- during initialization phase the cpu stays at around 35% and pending 
connections ramp up :

- but after all 6000 connections are in pending mode, the cpu usage is now 99% 
and closed connections start increasing:
