Is there any risk that the layers_ list may be modified between this check and the time when the layer is used?
The lock may need to be held during the entire operation. Or it may need an approach such as:
- with the lock held:
- obtain a layer if available and remove it from
layers_
- obtain a layer if available and remove it from
- if no layer was available, then create a layer
- with the lock held:
- set up the layer and insert it into
layers_
- set up the layer and insert it into
