The code tries to grab struct mutex for 5ms every time the unlocked GPU
idle wait succeeds. But the GPU idle wait itself is practically unbound
which means the 5ms timeout might not be honoured.
The arbitrary timeout is merely advisory. If we hang, we get to recover
everything we can!
You mean if we hang, eg. take more than 5ms to idle, the function bails
out on the 5ms timeout check, failing to take the lock and free anything? ;)
