there's two issues here: * arc prompts shouldn't cause moz-phab to freeze * binary files should be handled automatically looking over arc's code it appears that if we connect the subprocess's STDIN to a pipe arc will throw an exception instead of waiting for a response. look for `phutil_console_require_tty` in libphutil's `src/console/format.php`.
