Banana -- s-exp based protocol.

Future Plans: This module is almost entirely stable.  The same caveat applies
to it as applies to L{twisted.spread.jelly}, however.  Read its future plans
for more details.

    Set the limit on the prefix length for all Banana connections
    established after this call.

    The prefix length limit determines how many bytes of prefix a banana
    decoder will allow before rejecting a potential object as too large.

    @type limit: C{int}
    @param limit: The number of bytes of prefix for banana to allow when
    decoding.
