I'd be tempted to blame bug 727965, but it looks like that landed 10 hours before this started. Maybe bug 1084421? That landed a few days before this was filed, but presumably the sheriffs just didn't file new oranges over the weekend.

Olli, what do you think? This test does involve events. ;)

This stack looks very familiar. We're triggering a GC from inside an Unlink.

So yes, we'd trigger GC possibly a bit less often, but I'd say this is effectively a dup of bug 1087799.
