Since BUFSIZ is obviously chosen as an integral number of hardware
memory pages, the extended_buffer uses two pages plus two bytes. How
about allocating a buffer of BUFSIZ bytes and using only BUFSIZ-SL for
the string and the remaining SL bytes for the terminator?

I realize that at this point we're down to nitpicking because the
program seems really good and fast now.
