In many interactive applications (e.g., editors or form/menu systems),
users are not always interested in the intermediate screens,
only in the final screen after a long sequence of typed inputs.
Since these are popular curses applications,
type ahead checking was made the default behavior for curses.

Yes. After initscr(), call typeahead(-1). This turns off the typeahead
checking algorithm (by setting the type ahead file descriptor to -1).
