This bug is probably at least related to why trying to load https://archiveofourown.org/media/Books%20a%20Literature/fandoms in the 2017-04-14 Windows nightly build uses 2.2+ GB of RAM before crashing due to OOM. Let me know if I can acquire any more data to help diagnose this.

I don't see the extreme memory usage anymore, but I see #18690.
