Replying to myself, it seems that if I do an ssh and cat a bunch of data
from /dev/urandom through strings, eventually, the tunnel cant keep up and
data stops streaming. Funny enough though, if I hit a key, it still sends
data. It seems as if the ssh session got out of sync. Another ssh session
running simultaneously, but not actively communicating, remains happy once
the other dies.

I realize ssh probably isn't the best thing to test with, but it happens to
be a quick and easy way to test file sending. The question is, is our tunnel
acknowledging corrupted packets instead of asking for resends? The question
I'm asking ultimately is, what would cause corruption of the ssh session?
