well, one way to account for this overhead is to set the allowed bandwidth low 
enough. Being precise on this overhead lets you get closer to the actual line 
rate, but if you have enough bandwidth, it may not really matter (i.e. if you 
have a 100Mb connection and only get 70Mb out of it, you probably won't notice 
unless you go looking)
