Yeah, "unlikely"... we'll remember that one day ;-))
Well then, when do you want to do the sorting? Sorting takes N log N, and it 
would have to be redone everytime nextUrl() is called just in case something 
else changed it. So to me a linear walk-through sounds better, no? Unless you 
can guarantee that throughout the usage of that view the order won't be 
changed.

Sure, the order doesn't matter at all right now, and nothing is preventing us 
from changing it. Just not sure if we need to...
