Question: crash or get so slow it doesn't even refresh?

Well, what that means is that the client isn't responding to the server
fast enough so the server send buffer gets full. Since the client isn't
responding, the server cuts his connection. Which is nice. Better than
like it was before the network changes where it would lockup the server
for 30 minutes.

Well, i don't see how moving faster can be a bug :-)
I thought you wanted more performance?
Its probably an interaction from the Linux kernel scheduler, X, or something.

Integer overflow maybe? I dunno if we are using short ints for that.

I believe you are correct on your assessment.

Well, i have been planning to add slightly better networking to the
client, but i've decided to postpone it until after GTK+ 2.0 comes out.
There is a much worse bug in the client than the ones you mentioned, but i
will save those for after GTK+ 2.0 too.
