Don't need to. All versions of Bash that I'm aware of do this already 
unconditionally. Here's part of bshspawn.c that shows what Bash does:

  /* disable interrupt */
  old_enable = __dpmi_get_and_disable_virtual_interrupt_state ();
  old_ctrl_c = __djgpp_set_ctrl_c (0);

  /* check empty dpmi selectors */
  selectors = dosutil_check_dpmi_selectors ();

  __djgpp_exception_toggle();

  errno = 0;

  /* Run child process. If the filename doesn't have a period, add one
     to prevent __dos_find_on_path from finding a different file than
     intended.  */
    status = spawnve (P_WAIT, path, args, envp);

[snip]

  /* disable interrupt */
  __dpmi_get_and_disable_virtual_interrupt_state ();

  __djgpp_exception_toggle();

  /* free discarded dpmi selectors */
  dosutil_free_dpmi_selectors (selectors);

  /* Reset standard input */
  dosutil_reset_console();

  /* enable interrupt */
  __djgpp_set_ctrl_c (old_ctrl_c);
  __dpmi_get_and_enable_virtual_interrupt_state ();


In case you're wondering, 
dosutil_check_dpmi_selectors/dosutil_free_dpmi_selectors is Daisuke's hack to 
slow down the leaking of DPMI selectors.
