Interesting idea. We could look at the system urls that actually are 
aliased on a particular site, try to abstract some regexp from them 
(mainly by replacing numbers by a regexp matching numbers, I'd think. 
Maybe also by truncating them.) and store the resulting regexps in a 
variable. Then, before we'd look for a matching alias for a particular 
system url we can first match that urls against our regexps.

I somehow doubt that this would be faster, though.
