script to kill apache 1.3 / 2.x prefork httpd processes serving preconnect connections, in an attempt to prevent chrome from causing a DoS against the httpd

This is version 2 of https://gist.github.com/eqhmcow/4774549

The major change is the use of two processes instead of one:

One process makes server-status requests, the other kills idle prefork processes.

This allows the kill script to continue killing idle processes even when Chrome has effectively DoS'd the apache server. When this happens, the check script can't get an updated status response back immediately, but the kill script can hopefully free up a slot by killing some processes. Having an uninterrupted request in the socket queue allows us to get an updated response after killing the Chrome preconnections are killed.
