    Adjust ulimit on RPM platforms
    
    The default number of processes/threads (ulimit -u) on rhel6 and clones
    is 1024, which is too little for varnish.
    
    This patch adds a variable NPROC to sysconfig/initscript suppport in the
    rpm package. If no value is set in sysconfig, it will be set to 10000.
