Tbh I'm not sure when it is needed and when it isn't, so I chose to go
for the safe option. I know the read of device->device_state should be
atomic if its address is 4 byte aligned (and if it isn't
InterlockedCompareExchange won't help). But on the other hand you've
used it for read-only access in the fence implementation in your
command stream work. What was the reason for that? Preventing the loop
from looping over an unchanged register?
