Remove unused variables verbose-io? because it's never changed.
don't export display-message because it's not safe when writing to the output port. It should be an internal function. It's also never used outside the module.
rewrite the display-message function to make it clear and slightly faster.
fix a bug that the specified output-port of display-message/flush isn't passed to display-message correctly. It makes test-main runnable again.
