I did some micro-benchmarks and the URI class does not perform too
badly -- although it is clearly slower. I did a loop to construct a
million objects and see how long it took:

String class: 0.417
URI class: 3.968

I then took the loop and added a call to a method that took a String
and just did a couple of simple checks of the String to make sure the
compiler was not optimizing away any problems. That gives:

String class: 0.455
URI class: 4.003

That said, in this example, if this were someone retrieving History
entries that would be 4 more seconds added to the UI wait. Granted it
might have been a minute or more to get these million entries from the
server, but it is still added time.
