It's currently available in jabber.org's CVS (HEAD "jabber2" branch) or on download.jabber.org as jabberd v1.2 final.

The issue goes like this... I'm using a static read buffer (was 1024 bytes) to read from the socket... It would reduce server performance to make this a dynamic sized read buffer, (to go along with the amount that the karma will allow to read), so I just kicked this up to 8K (8192 bytes), which is a full read of 81 karma, (almost a full for 82 karma)... That's all I meant by that line...
The only other option would be to keep mallocing/freeing a read buffer for every read call, and that is just too expensive for the server to process, in the i/o loop.. especially if you have 100K sockets you are reading from.
