Mea culpa; I messed up part of the concat change.

I don't think this is actually a memory leak; the function to send data to
the network actually frees the buffer it was passed after the data has
been sent.  It's sort of odd, but it seems to work.

Thanks, applied.

No anonymous CVS, I'm afraid, but we do have CVSup access.  Here are the
details.

Using CVSup

    If you want to get updated INN source more easily or more quickly than
    by downloading nightly snapshots, or if you want to see the full CVS
    history, you may want to use CVSup to download the source.  CVSup is a
    client and server designed for replicating CVS repositories between
    sites.

    Unfortunately, CVSup is written in Modula-3, so getting a working binary
    can be somewhat difficult.  Binaries are available in the *BSD ports
    collection or (for a wide variety of different platforms) available from
    <ftp://ftp.freebsd.org/pub/FreeBSD/CVSup/binaries/> and its mirrors. 
    Alternately, you can get a compiler from <http://m3.polymtl.ca/m3/>
    (this is more actively maintained than the DEC Modula-3 compiler) and
    the source from <ftp://ftp.freebsd.org/pub/FreeBSD/CVSup/>.

    After you have the CVSup client, you need to have space to download the
    INN repository and space for CVSup to store its data files.  You also
    need to write a configuration file (a supfile) for CVSup.  The following
    supfile will download the latest versions from the mainline source:

        *default host=inn-cvs.isc.org
        *default base=<data-location>
        *default prefix=<download-location>
        *default release=cvs
        *default tag=.
        *default delete use-rel-suffix
        inn

    where <data-location> should be a directory where CVSup can put its data
    files and <download-location> is where the downloaded source will go. 
    If you want to pull down the entire CVS repository instead (warning:
    this is much larger than just the latest versions of the source), delete
    the "*default tag=." line.  The best way to download the CVS repository
    is to download it into a portion of a locally-created CVS repository, so
    that then you can perform standard CVS operations (like cvs log) against
    the downloaded repository.  Creating your own local CVS repository is
    outside the scope of this document.

    For more general information on using CVSup, see the FreeBSD page on it
    at <http://www.freebsd.org/handbook/mirrors-cvsup.html>.
