title: Running another program in Windows bat file and not create child process
body: <p>I have subversion server with a post-commit hook to do something.</p>
  
  <p>I want the checkin finish soon, not wait the hook script. 
  But by design, the Subversion post-commit hook script will run until all <strong>child</strong> process exit, so using somthing like:</p>
  
  <p>start another_prog...</p>
  
  <p>in the hook bat file has no use.</p>
  
  <p>So I want to know how to run another program in Windows bat file which not create child process or let the child process detach from the parent.</p>
