Maintenance4 contains the maxBufferSize property that contains the maximum allowed buffer allocation. This PR uses this property to precheck if allocations will fail. It was an attempt to improve the reliability of failing allocations but currently they fail at the driver side. Pull Request: https://projects.blender.org/blender/blender/pulls/145555
