I am wondering if there should be a default at all for N here as it seems
like it is not really possible to make a good decision as to what that
default value should be at the library level. If anything, I'd suggest at
least having the default value able to be easily changed by users of the
library with a #define. That raw, magic 256 at such a level is just a little
scary to me.
