My first guess is that you're piling up "end" marks.  Every time your  
IO watch fires, you create a new mark.  Actually what you want to do  
is create that mark once, when the buffer is created, and either keep  
a handle to it or request it by name.  If you create the mark at the  
end of the buffer with "right" gravity (which is exactly what you're  
already doing), then text inserted at that mark will always push it  
to the right, effectively keeping it always at the end.
