[development] Caching, caching, caching...

[Khalid B]

What Ken Rickard said makes me think of another solution:

If we provide a generic way to exclude certain paths, that can cut down
the processed aliases.

For example, a site may only want to alias "taxonomy/term/*" and
"node/*" and nothing else.

Another site may only want aliases for "node/*" and "user/*"

The code this way is generic and customizable on a per site
basis with no patches, ...etc.

You get the idea ...
