Yea, it would certainly be nice to not have to worry about UDP =
connections. They don't work for NFS in high speed high bandwidth =
workloads due to the issues with fragment reassembly. Their use for NFS =
v3 sideband protocols doesn't really buy much.

Of course we'll still have to support UDP for 10 more years...
