in fact that the testurl is effectively DOSed or not does not seem to matter,
the CPU usage reach 99% anyway after a while and then stay there. For example i
have 0 connection pendind, say 1500 connected and the site still up, and the
500 connexion closed and counting. All the time the slowhttptest will stay
runing from there it's CPU usage stays at 99%.

OMG, I am sorry, seems like google code doesn't notify me of new issues
reported.
Indeed, with 2K connections CPU usage goes up to 99%. Looks like something is
wrong in the logic once server starts closing the connections.
Thanks a lot for noticing, will fix this in upcoming release.

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