[development] modules admin page still eating 1.5 times the memory?

Hey, scor notes at http://drupal.org/node/197720#comment-648567 that the modules page (in Drupal HEAD) still eats 1.5 times the memory when compared to the default home page. This looks quite scary, given what we would expect with all the .info file trickery, don't you think? It would also be good to invesitage what eats so much more memory in Drupal 6 compared to Drupal 5, especially that we moved a lot of code into conditionally included parts, so those should not be in memory. Others reproducing the above test (and especially more thorough experiments) would be highly appreciated. Gabor
