Does SL's client / server network code run TCP over UDP? If so, why? What are the advantages of such a system?

Second Life currently uses mostly UDP. 1.9 introduced some TCP paths between servers, but not in the client. We use our own 'reliable' UDP message system mostly. In retrospect this is not the best solution, hence some of the changes in 1.9. Future updates to SL are likely to introduce more TCP and other standard communication methods in place of our current home rolled solutions.
