Anyone know what this is for?  I didn't see any mention of it in window(7),
but curses must find it useful:

    % grep ESC /usr/include/sys/window.h
    #define	WIOCSESC	(WIOC|17)	/* set double esc mode */

Also, from curses(3x):

    "In order to initialize the routines, the routine initscr() or
     newterm() must be called before any of the other routines that deal
     with windows and screens are used.  [...] The routine endwin() must
     be called before exiting."

Apply this patch:

  	sleep(1);
  	ioctl (0, TCSETA, &origtty);
  	exit(0);
