You specifically mention "sending" -- if you write 8192 more packets
than you read, and you're not using SELF_DISCARD (sp?), you'll fill up
your own receive buffer and spread will disconnect you.  It's not very
verbose about why it disconnects you -- that would be a nice area for
improvement -- so this is just a guess.
