You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: seccomp.rb
    path of file: ./repos/danbooru/app/logical
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# This is a wrapper around seccomp, a Linux kernel feature used to limit the
# system calls the current process is allowed to make. This is used for
# sandboxing 
    
    def apply_to!(&block)
      raise ArgumentError, "Seccomp::Filter#apply_block!: block required" unless block_given?

      pid = Process.fork do
        apply!
        yield self
      end

      pid, status = Process.wait2(pid)
      if status.signaled? && Signal.signame(status.termsig) == "SYS"
        raise Error, "Subprocess called unauthorized syscall (see dmesg for details)"
      end
