| DoSes too.

Oh GREAT.. so let see... i should go around the world changing all the hardware
on the planet because each user on a machine can use ab or any kind of tool
that can telnet to port 80 generating millions of requests on the localhost
server? Therefor slowing down the machine? You are welcome to provide me
the money to do so, together with patches to each config file for each
apache server out there so that there will be always available resources.

| IMVHO, You should at least read the bugreports before You are closing
| them...

So let see.. provide me a PoC that i can use to gather information out
of this theorerical bug that can lead to DoS or privilege escalations
and i will fix this bug immediatly.
