Work around bad choice for Apache::SizeLimit::Core policy on old CentOS

gistfile1.pl

use Apache::SizeLimit;

BEGIN {
  ### Don't try this at home kids...
  # this version of CentOS is too old, no read-access to
  # /proc/self/smaps unless you are root
  no warnings;
  $Apache::SizeLimit::Core::USE_SMAPS = 0;
  *Apache::SizeLimit::Core::_platform_check_size =
    \&Apache::SizeLimit::Core::_linux_size_check;

  Apache::SizeLimit->set_max_process_size(120_000);    # Max size in KB
  Apache::SizeLimit->set_check_interval(1);
}
