 Not saving {depends} to the index, using a hash instead of a list to
 de-duplicate, and allowing add_depends to take an arrayref instead of a single
 pagespec had no noticable positive or negative effect on this test.

 Memoizing the results of pagename brought the rebuild time down to 14.06s
 and the refresh time down to 7.96/7.92/7.92, a significant win.

 Refactoring to use pagespec_match_list looks more risky from a code churn
 point of view; rebuild now takes 14.35s, but refresh is only 7.30/7.29/7.28,
 another significant win.
