[tahoe-dev] large file (500mb) connection lost to the helper

Actually, looking at it again, 24.5% of 500MB is not 100MB, it is closer 
to 125MB, I somehow was assuming a 400MB file upload. So, this is 
probably not due to some exact file size, but maybe to do with a timeout 
that occurs at around 200Kbps * x = 125MB?

My timeout last night occurred at about 1hr20min. The "x" above is about 
80min which is almost exactly the same time spent.
