Comment 1 for bug 531071

I checked the logs (https://devpad.canonical.com/~salgado/leak.txt) from the period when we saw the spike in memory usage and created this spreadsheet to be able to easily sort them: https://devpad.canonical.com/~salgado/leak.ods

We were hoping to find some suspiciously-looking requests there, and there are a few indeed, but when a tried hitting (a freshly restarted) staging with them, we didn't see any increase in memory usage: https://pastebin.canonical.com/28709/
