[p4] Improve robustness on poor networks?

[Chris Weiss]

Our network's a bit spotty - if our pipe to the outside world gets
saturated, we start losing packets. This spells trouble for our remote
office as they'll be in the middle of a big sync and P4 will throw a
WSAE_TIMEOUT.

Does anyone have any tips (outside of QoS) on ways to avoid P4
dropping connections so easily? We've already got a proxy server in
the remote office, but it still disconnects far too often due to
packet loss.
