this is such a common operation. It would be nice if there were some 
optimized function to turn a mysql result object into a php array.

This happens in drupal_get_path_map(). Is there any reason why

this would be possible if we left placeholders in the HTML and then 
replaced with aliased urls right before we print the page. In order to 
do so, we need some significant changes though:

- modules always return output instead of printing theme('page')
- add a 'replace url placeholders' step before calling the theme('page')
- somehow replace placeholders for links emitted within the 
theme('page') like html_head, blocks, etc.
