This will allow us to handle the escape key (or maybe meta) sooner. The input received by the escape key is actually the same as the first characters of e.g. Arrow-Up, so without knowing what follows the escape sequence, we don't know whether escape has been pressed, or whether it's something else. This flush function should be called after a timeout, and processes everything that's still in the buffer as-is, so without assuming any characters will follow.
