Until recently, I didn't change the meshes for existing objects much. Now, I'm creating and releasing meshes and objects at a high rate as the viewpoint moves around, for level of detail management purposes. So Rend3 is being exercised in a new way.

Another one of the same. It's intermittent, but not a one-off.

This time with the fully arcanized version. rev = "a68c76a".

[John-Nagle]

These occur frequently now in complex scenes. rev = "a68c76a", which I now know is not arcanized.

[John-Nagle]

Still fails in arcanized version rev = "c7c2d85":

https://github.com/gfx-rs/range-alloc/issues/1 seems to fix this. Survived 8 hours of testing so far. Never got past 2.5 hours before. I'll let it run overnight.
