It's interesting to try. In non-interactive mode, `make-frame' crashes
with "I/O possible" (receiving a SIGIO I guess) when making a GUI frame,
and segmentation fault when making a TTY frame.
I.e.
emacs -batch -eval "(make-frame '((display . \":0\")))"
emacs -batch -eval "(make-frame '((tty-type . \"xterm\")))"
