Prior to this patch, this was done in one query to fetch the maintainer IDs, and then one query per mainatiner to get the name/email address. Now, with this patch, it's all in one query (yay joins) and saves a few ms of database queries for displaying the page. Realistically, this doesn't save us too much time as counting how many patches are there takes 99% of the database time for this page.
