This is a shutdown hang happening in Servo code while destroying a document. We noticed this issue in content shutdown hangs too (see this signature). From the looks of it I don't think that we're stuck in this code, it's just being slow which explains why we have multiple slightly different signatures.

Going to P3 this for now since it's a shutdown hang, and to match bug 1613797.
