It's a known bug.  It's a race condition.  Changing
`_xwin_close_display' (in src/x/xwin.c) to this seems to fix it.


void _xwin_close_display(void)
{
   Display *dpy;

   if (!_unix_bg_man->multi_threaded) {
      XLOCK();
   }

   if (_xwin.display != 0) {
      _xwin_destroy_window();
      dpy = _xwin.display;
      _xwin.display = 0;
      XCloseDisplay(dpy);
   }
      
   if (!_unix_bg_man->multi_threaded) {
      XUNLOCK();
   }
}


Someone else should commit it, after some testing.
