The current documentation on the Rlimit{CPU,MEM,Nproc} directives

uses the wording "for all processes", which leads one to believe that
the limit applies to all of the Apache children processes.
However, this is not the case. The resource limits are applied in
ap_call_exec() which is only called by mod_cgi and mod_include.
