Hard to repro. Keep loading heavy meshes, sometimes the app will hang and crash due to the Vulkan device being lost.

Possible causes:

Multi threading errors
- Validation should be catching concurrent use of resources?
- Fence status / wait has caused issues before: do a pass on these
Driver bug
- Try to repro on Windows
