I had similar problems to think of with the big A. Due to the IGS 
protocol there aren't really any easy nor perfect solutions possible. In 
A I  (not AI :) )  I buffered some commands - basicly if IGS doesn't 
respond in one second Ambassador sends the command again every second 
until IGS responds. However I only implemented buffering for commands 
needed when a new board was opened and for the player list - I just 
didn't bother to buffer the "games n" commands. This works well, however 
there can be some problems (w/ the player list) if the number of IGS 
players rises by a factor of 10 or so for obvious reasons.
    Anyhow, I don't think you should really bother your mind too much 
with this. I spent too much time trying to make a perfect buffering 
until I realized it is not possible (at least AFAIK and with the older 
versions of IGS server software). There are more imporant areas of 
developement.
